It is not just that they look like their astronaut counterparts though.
Or that they all have the same names.
Or that they are all roughly 30 years older than the astronauts were when they dies 30 years ago...
As if those coincidences were not enough.
The double of the Captain of the Challenger, Richard Scobee, is CEO of this company
www.cowsintrees.com - you should see a flash animation when you first visit that site.
If the coincidence of a man looking like Capt Richard Scobee, being a similar age as Richard Scobee would be now, being called Richard Scobee wasn't an amazing enough coincidence - being the CEO of a company whose website that opens with a rocket launch and then a swirl of white smoke against a blue sky. Regardless of how much you pass it off as coincidence that is one hell of a freaky coincidence. Anyone who says the caterpillars of swirling smoke against the blue sky isn't the first visual image they have when thinking of the Challenger explosion is a liar.

A conspiracy theorist may see that as hiding clues in plain sight...
I, from the start, have asked why you would let them live on with the same names, so leaving clues like this as well would be ridiculously stupid.
Do I honestly think these folk are the Challenger crew. No, probably not. They could be. But I doubt they are.
Regardless, the number of coincidences combined to create a scenario whereby four members of the seven crew could have doppelgängers with the same name, at the right age and whom have curious/coincidental links to the Challenger story... That is something in itself, whatever it is.
