Talk:Tupolev Tu-2000

Speed?
Article says top speed is Mach 24 in space... I think this article should define the speed of sound in a vacuum to ensure no-one misunderstands this information. —Preceding unsigned comment added by 80.6.35.235 (talk) 23:02, 26 July 2010 (UTC)

Powerplant
The specifications section states that the powerplant was planned as 6 × liquid hydrogen with liquid oxygen oxidizer turbo jet/scramjet.

But a jet engine - using conventional terminology - uses atmospheric oxygen as oxidiser; if you're carrying your oxidiser, then you're a rocket engine (if you see what I mean).

Something's not right. I don't have the book used as the supposed source of this claim.

Anyone?
