STENDEC: Airliner 'Star Dust' Lost In the Andes (1947)

Why would it? I mean.. there are times that people can with sheer will try to make sense when nothing's making senes - could be he lost concentration towards the end of the message there and couldn't articulate properly. Just a thought.
 
Just seems unlikely - overly complicated - IMHO...
 
Epic but interesting.....

When it comes to airline crashes, few have posed as many unanswered questions as the Star Dust. Originally scheduled to fly from Buenos Aires, Argentina to Santiago, Chile, the Star Dust disappeared on August 2nd, 1947. However the flight would never reach its destination and the fate of the British South American Airways (BSAA) Lancastrian 3 airliner would remain unknown for over 50 years.

The Star Dust’s manifest showed six passengers and five crew members on board flight CS59. Reginald Cook, the captain, was a distinguished Royal Air Force pilot with extensive combat experience in World War II. Cook’s first and second officers were also war veterans with combat experience.

The passenger list certainly does its part to set the stage for conspiracy theories: A Palestinian returning to Chile from visiting a dying relative, two British businessmen, a high-ranking associate from the Dunlop tire company, a British civil servant delivering important documents to an embassy, and a German-born Chilean resident who had been stranded in Germany during the war.

The flight departed Buenos Aires at 1:46 p.m. on August 2nd, headed over the Andes mountains. Before the airliner’s disappearance, the flight was uneventful. The final transmission from the Star Dust to Santiago’s airport was a Morse code transcription, S-T-E-N-D-E-C, the meaning of which has been debated by experts since 1947. Santiago’s Morse operator asked for clarification, and twice more S-T-E-N-D-E-C came through the wire.

There are many interpretations of the meaning; one hypothesis is that STENDEC was an acronym (Starting En-Route Descent or Severe Turbulence Encountered Now Descending Emergency Crash-landing). Others suggest perhaps the Santiago Morse operator misheard and thus mis-transcribed the code. Still others point out that STENDEC is an anagram of DESCENT. To this day, no one can definitively say what the Star Dust’s Morse operator was intending to say. What is known, is that the Star Dust would not be heard from again. After the tower received the STENDEC call from the Star Dust there was no more communication from the aircraft, and it never reached Santiago.

Search teams scoured the mountains but found no clues as to the whereabouts of the Star Dust. The complete lack of evidence combined with the odd STENDEC transmission invited some to speculate that alien UFO activity might be responsible. Others opined the flight might have “overshot” Santiago and plummeted into the Pacific Ocean.

For 51 years, that was all the information we had on the disappearance of the Star Dust.

Finally, in 1998, two Argentinean climbers ascending Mount Tupungato of the Andes – about 50 miles east of Santiago – came across some wreckage of an airplane engine. They found additional twisted pieces of metal along with shreds of clothing and other airplane parts. They returned to Santiago and reported their finds immediately, and suddenly the mystery of what happened to the Star Dust was thought to have been solved.

It wasn’t until 2000 that a follow-up expedition could be conducted, but the Argentinean army expedition found the crash site along with additional wreckage: wheels and propellers. They were also able to discover human remains which were tested for DNA in 2002 and confirmed to be those of the passengers of the Star Dust. Experts were able to identify the accident as a crash rather than a mid-air explosion due to the localization of the wreckage. Also, since the wheels were retracted at the time of crash, authorities surmised that the Star Dust was not attempting a crash landing at the time of impact.

Once it was determined that the Star Dust had crashed into the side of the Mount Tupungato, the process of beginning to figure out why commenced. It is known that there was a snowstorm at the time and cloud cover was intrusive. The most common suggestion is that Captain Cook encountered a jet stream at altitude, and that the jet stream carried the airliner slightly off-path so that the captain thought he was clear of the Andes when he had yet to cross them. Being surrounded by clouds limits the captain’s abilities to perceive his own location, and that combined with the jet stream can send an aircraft significantly off course. It is thought that Cook assumed he was clear of the Andes and began his descent early.

So how had the Star Dust been hidden for over 50 years? It is likely to have flown into a nearly vertical glacier, causing an avalanche that buried it within minutes and concealing it from rescuers. The wreckage was entombed in the ice and was hidden until the ice had made its way down the mountain and slowly melted. Only about ten percent of the wreckage has emerged from the mountain with experts suspecting the remaining wreckage to make appearances in the future as the glacial ice melts over time.

The ultimate investigation cleared the captain of any wrong-doing, concluding the crash was a result of poor weather which resulted in the crew being unable to correct their positioning.

What do you think about the Star Dust’s crash and surrounding investigation? Happy to hear it wasn’t aliens or terrorist activity?

I've always thought it was a misspelling under pressure of bad weather etc. of 'DESCENT' . It's happened to me with passwords - you spell it wrong, but are so urgent to get on with what you are doing you think 'fool machine' and automatically retype it the same way without thinking. With morse it would be even easier to think 'darn fool' and send the same sequence without questioning that you had it right.
 
Saw the Horizon documentary about this again yesterday. Has anyone come up with anything fresh on this in the last few years?

I've looked around but not come across anything particularly convincing.

... offers one possible explanation for the 'STENDEC' message (involving misinterpretation on the part of the Santiago radio operator), but cites an even better (and later-arriving) theory from a Martin Colwell in Canada. Colwell's theory (also based on radio operator misintepretation) is described on this webpage:

http://www.sartechnology.ca/sartechnology/ST_STENDEC_ColdCase.htm

Bottom Line: In both cases 'STENDEC' has been a mystery because 'STENDEC' wasn't the message that was sent - it was the misinterpreted message the Santiago operator recorded. Under both theories the intended message was notification of approach to the Santiago airfield, sent under the erroneous belief the Star Dust had cleared the Andes.

Colwell in particular blames the misinterpretation on the message having been transmitted at a higher speed than operators were expected and certified to handle.
 
I suspect the 'Stendek' video is BS of the highest order, at least to the extent it tries to link 'STENDEC' to the Bermuda Triangle.

Stendek was the name of a Spanish UFO magazine published in the 1970's and very early 1980's.

sten_magazines_l.jpg

The video produced by 'Stendek LLC' may well have mis-attributed 'Stendek' to the Bermuda Triangle based on a notably sloppy piece of work entitled:

Enigma Fantastique
By W. Gordon Allen, 1966

If you check the account in this tome at Google Books:

https://books.google.com/books?id=L...ECCkQAQ#v=onepage&q="stendek" florida&f=false

... you'll find the following:

- Allen attributes the term 'Stendek' (sic) to the 1947 Stardust incident;

- Allen obviously missed the fact the 1947 radio transmissions were conducted in Morse Code, and he erroneously claimed the airplane's pilot (Cook) verbally repeated the word 'Stendek' (sic) 3 times before transmissions ceased.*

* NOTE: There's no reasonable way to distill 'STENDEK' from 'STENDEC' in Morse Code unless the sender missed a final 'dot' three times in succession. The Santiago airfield receiver noted the message as having the final 'dot' (i.e., ending with a 'C') three times in succession.

- Allen proceeds to generalize and redefine this mistaken misspelling into what he calls 'Stendek conditions' or 'Stendek encounters', then changes the subject to the Bermuda Triangle.

- Allen makes no mention of a Bermuda Triangle aircraft disappearance in which the mystery term 'Stendek' was transmitted. It is whatever-it-is motivating panicked radio transmissions per se that constitutes one of his 'Stendek Conditions'.

- Allen transplanted the same text near-verbatim into his 1974 publication Overlords Olympians & The UFO:

I remember this at the time... any help here?

Dunning's account gives up on the notion of a Morse Code misinterpretation, except for his mention of a possibility the transmission started with 'VALP' - ostensibly a reference to Valparaíso. However ...

There were two airfield code lexicons in effect as of 1947 - IATA and ICAO. Neither assigned 'VALP' to Valparaíso's airfields.

Dunning never seemed to have considered that the opening letters (ST) could have referred to a Santiago airfield. The 1947 flight was planned to land at Los Cerrillos Airport (ICAO code SCTI).

Fabulous posts from your good self on this. Thanks for taking the time.
 

The most significant thing this article adds is an allusion to one of the many theories as to what message the radio operator Harmer was actually sending - i.e., "Severe Turbulence Encountered, Now Descending, Emergency Crash-landing".

This and many other hypothetical interpretations are described at:

https://www.pbs.org/wgbh/nova/vanished/sten_010208.html

The "Severe Turbulence ..." theory is attractive because it allegedly reflects a standard message known to have been used by pilots escorting ship convoys in the North Atlantic during WW2. However ...

One must wonder why an experienced air crewman would send a WW2 Anglo-American specific acronym to a Chilean radio operator during peacetime and expect the receiver to understand it.
 
Worth a mention?

Hmm. I have *never* heard of this -
"Severe Turbulence Encountered, Now Descending, Emergency Crash-landing". Are you sure it existed @EnolaGaia

Highly-doubtful. I call it as an internet-generated backronym.

If this had really been a WW2/post-war flight safety proword, the many experienced demobbed aircrew in civilian life (including civil aviation) would've instantly recognised it- so how would there ever have been a "mystery" perceived surrounding the sent word in the original post-incident instance?

Mmmm... see what you mean...

Duly, therefore, count myself in as well!

Check my earlier post - I said 'allegedly'.

I've never run across this purportedly stock phrase except in relation to the STENDEC incident. If it was a convention for convoy air support personnel during WW2 it may not be documented. In any case, why not simply use a 'Mayday'? Isn't the bottom line message 'Going down' rather than 'It's turbulent up here'?
 
The reason why I found this an intriguing discussion, was that I believed our enigmatic message to have been explained.

We need to go back some thirty years, or so.

Recall reading a related article, which explained how the same message input, correlated with another meaning, i.e., there was more than one interpretation of the characters sent and the input *also* could be a standard message, simply misinterpreted. Essentially, a standard message used the same 'input' and this was *clearly evidenced*.

Can I find this online...

You know the answer...

Anyone?

I think option two there SCITAR, is as convincing an explanation as will ever be offered. I think in fact that it wraps it up.

Although my post was made around three years ago this had continued to bug me periodically, I've been thinking about it this week as it goes. Thank you for posting that.

Exactly-so, and apologies- I >did not< see your 'allegedly' caveat.

And I agree totally, why would a company airline radio operator suddenly flip back to using a non-standard (both to era and service) distress signal.

I have a strong gut feeling that my theory about this being a nasty case of classic internet backronymic meta-ostension could be right.

Also: during the morse era (WW2 and post-war) flying radio operators in large multi-engine aircraft which were likely to be making a forced landing would *always* send a basic IACO-compliant distress location
¤SOS¤
¤Callsign¤
¤Location (& bearing)¤
¤Nature of emergency (and pilot's intent)¤
¤(POB)¤
¤(then...SCREW DOWN THE KEY)¤

At the very least, they'd send SOS/CALLSIGN/JAM the key down. I've personally shaken the hands of a number of RAF aircrew that actually did this....and I have no doubt the same logic would apply in civil settings (ie maximising the chance for ground stations to triangulate or at least get an approximate bearing). This was the baseline standard expectation for every RO in the back of any 1950s CW-only HF-fitted aircraft.

It is convincing, and I'll concede, if the Radio Operator (and Pilot) both believed they were on an inbound path to landing safely at that specific airfield, it needs further thought.

There's a danger that Martin Colwell of SAR Technology Inc and Lawrence Hooper (the experienced Radio Operator) may be getting slightly-skewed with the morse evidence.

The full correct morse for an exchange such as they're supposing would actually look more like this
SCTI SCTI DE GAGWH AR

'Station called, station called(SCTI), this is(DE) station calling(GAGWH), go ahead the Named station only(AR*)"

No radio morse user in the ITU aeronautical mobile radiotelephony service of the 40s/50s would ever NOT transmit their own callsign frequently.

The barred letters (A and R with a bar above them, to show send/receive combo as one continuous morse symbol). In fact, that's written more-commonly as 'KN barred' (exactly the same dots and dashes, but literally meaning 'K' (dah-di-dah: Go Ahead) followed by 'N' (dah-dit: Named station only)
 
I like this 'mystery'. Now we know what happened to the plane - they flew straight in to a mountain - it is of no consequence whatsoever but equally we can never (short of time travel) know the true explanation, mundane though it may be.
 
surely pro morse users can differentiate C = TEN and D = TI

Pro morse users familiar with the speed and 'style' of the sender certainly can. Using a manual key setup results in operators exhibiting personal idiosyncrasies in how they tap the key during a transmission.

One of the persistent points that stands out for me is that the Chilean radio operator described Harmer's transmissions as notably 'rapid' or 'fast'. The implication that Harmer's transmissions might have been faster than the Chilean operator was accustomed to, or could handle, is one reason so many people have considered 'STENDEC' to be a misinterpretation rather than a cryptic accurately-recorded string.

It does seem odd that re-interpretations of the possibly intended message(s) seem to eliminate any trace of the sender's call sign (or equivalent self-identification).

This in turn makes me wonder about a question I've never seen asked, much less answered, about the events of that night:

Were the famous 'STENDEC' messages the first and only Stardust transmissions received at the Santiago airfield that night?

It seems that every one of the many accounts I've read focus on the famous message set and characterize it as "the last message(s) sent from the doomed airliner."

If there had been earlier message traffic that might explain why Harmer didn't make a point to self-ID on the last transmissions.
 
surely that wouldve had military repercussions ?

I don't understand your question ... What would've had military repercussions? :dunno:
 
idiosyncratic morse transmissions during wartime ?

Yes - differences among operators would have been a potential source of performance or operational breakdowns or miscommunications in wartime (just as in peacetime).
