What he said was about as useful as a fart in a spacecraft.

3. ETH
Used by UFO enthusiasts as an abbreviation for "Extraterrestrial Hypothesis," referring to the belief of some that UFO reports represent sightings of alien spacecraft.
I neither accept nor reject the ETH. Quite frankly, I don't know what UFOs are - they're UNIDENTIFIED.
4. Roswellian
So advanced that it must have been derived from the reverse engineering of crashed/captured alien spacecraft, such as that said to have crashed in Roswell, New Mexico in 1947.
That new classified U.S. spy plane is loaded with Roswellian technology.
5. X-15
A 1 manned, rocket propelled air/spacecraft that can go over the Von Karmen line(space).

The x-15 is the shit because it can go into space.
6. Enterprise Effect
A phenomenon seen in many sci-fi movies/TV programs by which any damage to a spaceship (regardless of location) is seen as sparks and/or fire in the bridge/command center of said spacecraft. First experiences with the effect were on the bridge of the USS Enterprise, piloted by the illustrious/infamous Captain James T. Kirk of Starfleet Command (hence the name).
Scotty: We've 'ad an 'it on on the most unimportant part of the ship Cap'in. I can' hold her!

Kirk: Oh god, the sparks and/or fire are/is everywhere!!1 We're experienceing one hell of an Enterprise Effect.
7. lithobraking
Rapid deceleration of a spacecraft or other projectile due to impact, possibly unintentional, with a planetary surface. Compare to aerobraking.
The unfortunate confusion between Imperial and SI units caused a larger-than-expected atmospheric entry angle, resulting in a catastrophic lithobraking approach.
