Your question concerns glide ratio. Military jets tend to have
very low glide ratio, and very high wing loading. If you've ever
seen the wings on a glider, they are very long, and the glider is
very light. This essentially means that, on a glider, a lot of
wing does relatively little work, and the plane will glide a long
way forward without much loss in altitude.  Military jets on the
other hand, usually have very heavy fuselages and stubby wings.
This enables the jet to go fast without much drag from a lot of
wing sticking out into the wind. The downside is that they have
little to no glide ratio. When airspeed over the wings slows for
whatever reason, the wing "stalls" or quits flying, and the plane
drops, because it won't glide...it's just too heavy and the wings
are too small.

Hope that clears it up a bit for you Mark. Don't be too
disappointed, but I'm afraid good old aerodynamics are to blame.
