The 163 used 100% peroxide as the oxidizer. Nasty stuff that would
"burn" anything it could come in contact with.

F-16 doesn't glide any better than a lawn dart.

F-15 glides beautifully. I once rode in one that glided 75 miles from
flight level 400, in flight idle, joker fuel, to pattern altitude
without touching the throttle.
