"just one last attempt at r,a,s" :-

I consider this a totally pointless exercise (In difficult situations I
usually just jump, pull the string, and accept a broken ankle upon landing)
. . no pilot in the UK has ever been lost jumping from a stricken glider
(which is more than can be said of many who stayed aboard) . . therefore,
the official BGA statistically based advice is . . "If in doubt, jump" (you
know it makes sense, lol).
