I get the feeling you don't understand that a "Military Training
Route" is not ordinary see-and-avoid airspace. Rather, it's airspace
used in a special way, with military aircraft given exclusive use when
the airspace is active.
Other aircraft, including gliders, are supposed to stay out of the
route when it's active. This glider pilot didn't, and so was at
fault.
He was in an airspace forbidden to him then, an airspace dedicated at
that time to the use of high-speed aircraft. He wasn't expected to
dodge the fast-mover but to stay away from the airspace reserved for
that fast-mover. The reason the space is reserved is that it's hard
to get out of the way of a fast-mover, because there isn't enough time
between when you see it and when it's where you are for you to be
elsewhere. And the fast-mover doesn't have any more time to maneuver.
Maybe less, as gliders are smaller and, maybe, harder to see.

What??? Who gave you the misinformation? Tell me where in the FARs it
describes MTRs as PROHIBITED or RESTRICTED or EXCLUSIVE or RESERVED
airspace.
