OTOH I once tipped a rucksack out on a hostel bed in front of several other people and a condom fell out. My hard-won respectability was up in smoke on the spot.

They didn't believe the rucksack was second hand, bought off a former gap year traveller who'd obviously never got lucky...
Or of course he could have started off with a mega box of the things and got very lucky indeed.

Dont think I posted this at the time but a conversation yesterday reminded me of it.
Went to a funeral about 3 or so years back,
The service was taken by a lady Cannon, after the service we were invited back to a
pub about 8 miles from our village for a feed, when we were getting ready to leave
we were asked if we were going home and if so could we drop this lady Cannon off
as she lived near us, ok no problem, got in the car and though it started and ran like
normal 2 or 3 warning lights, engine management and such lit up, all went well stopped
outside her house she got out and the warning lights went off, connected a computer
but no fault registered and nothing has since, probably just one of those things but
strange at the time.

I've got a fitness bracelet (aka a 'fitbit', but that's its shorthand popular name, as in hoover/biro/tannoy etc).

It's very basic, but as well as just downloading my physical movement data to a semi-smart phone, it has been configured to go buzzbuzz/wiggle-waggle once I reach 10,000 steps. Depending upon circumstances, I may reach this point quite early in the day, or, more-commonly, later.

Recently, and strangely, I've begun pre-empting this happening. Not always, but often enough for it to be odd. Somehow I instinctively seem to just.....know, that it's about to buzz.

I'm not considering that somehow I'm counting steps in my head. Nor is it via cues from time-of-day etc.

My best non-supranatural theory is that somehow (sometimes) I'm subconsiously thinking about the bracelet, then when it does go buzzbuzz/wiggle-waggle I'm already half-primed (in some kind of perceptual sequence interpretation failure that is a mini version of deja vu) I therefore think I've preempted it. But I'm not convicing myself.

Comments? Ideas?

I'm a bit puzzled by this comment as surely that's the most likely? Not suggesting you are counting as such but after using it for a while surely your body will 'know' when it's about to go off?

Sat out in the garden this afternoon.

Watching a plane passing over on the high level route that passes South East to North over this area.
Anyway, the plane is about half way across my field of vision when another one appears behind it. Following the same route. The another and finally a fourth. All spaced out by five or six mile I would estimate.
Now, apart from the number of planes following each other (usually it's just two) what struck me was that behind the first three planes was a short condensation trail , But not behind the fourth one.

They were all apparently (going by the size) at the same height, and following the same path.

So Why didn't they all produce a trail ?

But how? I could walk / jog 8,000 steps, over a whole day, and perhaps be tired-enough to feel as if I must've walked nearly 10,000. But I've not....and my weird pre-emptive 'spider sense' about the fitness bracelet doesn't falsely-alarm me.

That's the whole point. I shouldn't know that I've travelled 10,000 steps. But (when I have walked, say, 9,995) something inside me says "that bracelet is going to go buzzbuzz/wiggle-waggle...." and it then DOES, fractional seconds after I've had the notion. I've no clues / cues to prompt this expectation.

And this is not a case of repeated unfulfilled false expectations. As in expecting-it-to-go-off-all-the-time-and-then-when-it-does-Wow....

If it's not going at alert me, I know that too. If I feel it's just about to alert me, then it just does. Maybe not explaining this perfectly....does anyone follow my rather-rambling exposition?

If the four planes were slavishly following the same path ...

Contrails are primarily the result of condensation coalescing on / in the engine exhausts. Secondarily, and to a lesser extent, similar but typically much smaller condensation trails can occur on or just behind the edges of a fast-moving aircraft such as a fighter.

At higher altitudes, such condensation is occurring within layers or strata which are relatively calm and humid.

One possible explanation is that the condensation caused by the first 3 planes dropped the localized moisture content to the point nothing condensed in response to the 4th plane's passage.

A related hypothesis would be that the passage of 3 planes in relatively close succession stirred up the air to the point condensation was forestalled for the 4th plane.

Another theory seems more likely to me ... The layers / strata within which such condensation occurs can be limited in extent (causing contrails to suddenly appear / disappear). It seems far more probable that the 4th plane was flying at a slightly different altitude placing it outside the "contrail condensation envelope".

Outside my comfort zone.
I've posted before about my missing money. Searched everywhere, it turned up in a notebook beside my bed, poking out and unmissable, even though I'd been looking for months.
This may seem like a dumb question but I have to ask: during that time, did you actually use the notebook?

Does your 'fitbit' do something just *before* it buzzes, that you pick up on, but that's so quick it's almost unnoticeable? Like some alarm clocks do a sort of 'ting' just before they ring, which wakes the sleeper who then thinks they always wake just before the alarm?

Planes on regular flights that aren't on approach or take off paths will (if not separated by tens of miles) be separated by some hundreds of feet in altitude to avoid the risk of collision.
They follow what is called 'the quadrature rule' (or something similar). Basically the ones going in one direction all fly at the same height. (or maybe some multiple, I can't remember) and those traveling at 90 degrees fly at this height minus a set number of feet altitude. The ones going in the opposite direction (say South) are at minus twice this altitude distance, likewise the ones traveling West are similarly spaced with regard to the ones going East.

So in theory the only planes at your height should be traveling in the same direction, and there should be little chance of collision.

This is why no one flies directly over the poles.

No. I wish it was that easy.

I even wondered if the fitbit *might* emit some Bluetooth radiofrequency energy, just prior to alarming, and that (somehow) I was detecting that. But I'm not convinced that it does- nor am I a strict believer in pseudoscientific 'electrosensitivity'.

However- I *am* open-minded as to all possible explanations. Because I think there's some degree of inexplicable actual perception going on....

The most highly trafficked corridors (both nationally and internationally) have long been organized in terms of well-specified and enforced "tracks." These tracks are essentially ephemeral superhighways in the sky. The most widely known example would be the NAT's (North Atlantic Tracks) along which transatlantic flights are guided.

Such defined tracks have specific paths, waypoints, turning points, and entry / exit points. For recurring scheduled flights a big chunk of the planning simply consists of repeating a sequence of track-related actions. For incidental one-shot flights the planning commonly entails submitting a request to the relevant authority and in effect being given a reservation. These reservations entail specific times and track locations - they're not simply "open access tickets" for free-form use of the tracks.

This doesn't apply in the same way to VFR flights. Hence the need for the Quadrature rule.

True, but ... In most developed countries even VFR flights are subject to spatial restrictions and requirements for coordination with ATC. Unless you're operating out in the boonies, it's still not completely free-form.

Going back to what triggered this.

The four planes I was watching were all of similar length, as viewed from my position. And this makes me believe that they were all at the same height.

The point of interest to me was why was the last one not putting out a visible condensate trail when the others were.

As an aside, planes using the same rout today are all leaving long vapour trails that are persisting for minutes after the planes have passed. Different conditions up there.

Meteorites were considered lunacy until 1803, when thousands of the impossible things fell in a French city [ https://www.smithsonianmag.com/smar...ped-establish-existence-meteorites-180963017/ ].

I would much rather go with my guts telling me about the presence of electric fields--something I could test by myself and falsify--than listening to some random internet stranger sneeringly patiently telling me about what I should be experiencing. Not that I am sensitive to electricity, but my tinnitus is annoying enough, and I'm sympathetic to your suffering.

I have mentioned this before in respect of the telephone at my previous house. I always seemed to sense when the telephone was about to ring, and wondered whether I was detecting some radiofrequency emission prior to the ring.

Maybe the heat from the planes in front had altered conditions enough to prevent the last plane producing them,
a difference in height of only a few hundred ft can make the difference.
One thing I have wondered about is that when conditions are just right you can not only see the con trail
but also a darker twin stretching out in front of the aircraft, it cant be there so must be some sort of optical
thing maybe a mirage or even just a shadow.

Ah ha! I've only noticed it the once, several years ago watching two passenger planes as (opposed to the usual screaming jets in the area of Wales I was living in) flying westwards with the sun halfway towards setting. It looked like the planes were following their own individual tracks in the sky as I couldn't see why shadows would be in front of them. I tried to work out how it could be happening but decided I didn't have enough knowledge about heights and angles of view and upper atmosphere conditions. It was fascinating to see.

I was meaning that your subconscious was taking note. Given that not all the stuff that's going on is noticed by our conscious mind. It's not so much about how you are feeling but how things are. After a few times of the bleeper going off a pattern was noticed and so you got the 'inner knowing' pre-alerts. I'm not saying that that is what's happening as I'm not the person experiencing it which could be quite different to how I'm imagining it and I don't know enough about neuroscience! :)
