Guinness World Records Recognizes NASA X-43A Speed Record (http://www.spaceref.com/news/viewpr.html?pid=14894)


Guinness World Records has recognized the world speed record set by NASA's hypersonic X-43A aircraft earlier this year in an experimental flight over the Pacific Ocean. Using a scramjet engine, the unpiloted, 12 foot-long aircraft achieved Mach 6.83 -- almost seven times the speed of sound - - or nearly 5,000 mph, in a March 27 flight.

Not for the first time, I'm sure:
Not even trying very hard to think of some:
- First man on moon
- First spacecraft to leave the solar system
- First manned rendezvous in space
- First spacecraft to visit Jupiter, Saturn, Uranus, Neptune

That's not a speed record though. The Shuttle comes in much faster, so maybe it's powered flight, or powered flight at that altitude... and the scramjet was unmanned! Rockets have gone much faster than that.

The X-43A flight easily set a world speed record for an air-breathing engine aircraft.

I think the key phrase is "air-breathing."

- first space based telescope (Hubble)
- first reusable space ship (shuttle)
- first live rescue of manned space craft damaged in space. (Apollo 13)
- Most mass launched into space
- Most space based telescopes launched
- etc.

Hardly ... try OAO2 (it would have been OAO1 but that broke shortly after launch)

Or, possibly, "aircraft" is the key word.

Yeah, I was going to jump in there, too. This one is on the list of things like 'the Sun is an average star'. And The New Scientist keeps repeating it too.

I suppose being picky, OAO should be 'first space-based astronomical telescope'. Technically, telescopic optics must have been built into some earlier spacecraft for star tracking - or maybe Earth observation (for example the Corona/Discoverer milsats)
