If you're going to pay tribute to Felix Baumgartner then you have to also have redbull in there, because after all, it was a professional stunt paid for by red bull.
And no one has yet suggested Ian Bell.
I think the Baumgartner thing was hyped up so much that it ended up looking like a stunt but there was a lot of very valuable science in there and some of the of the technology and lessons learnt was aimed at preventing (or at least reducing the risk) of loss of life in incidents such as the Columbia disaster....
Back to the recognition stuff...
Certainly agree with Ian Bell getting a mention and also I think ALL the Mercury, Gemini and Apollo astronauts should get a mention.
Mention should also be made of the names of the six shuttle craft
Enterprise
Columbia
Challenger
Discovery
Endeavor (American Spelling, sorry)
Atlantis
I also think that some of the NASA leading lights in the early days should get a mention... Those who got the program off the ground for want of a better phrase. These should include:
Bob Gilruth
Chris Kraft
Gene Kranz
James Webb
I'd also look for the following too:
Brian May
Sir Patrick Moore
Alan Turing
Charles Babbage
Sir Isaac Newton
Madame du Pompadour (Has to be a Ship out there called this after the Dr Who ep)
Douglas Adams of course...
I could go on but you're saved by the fact that it's waaaayyyy too late (or early depending on your viewpoint) for me to be up.... (it's gone half one in the morning!)
