whoa easy all. First of all I'm in no way trying to make light of the situation, degrade the quality of aircrew or MB abilities to save lives. So relax.
That said if the stat is correct that the RAF (never mind the other air forces taking Jaguar) have lost over 30% of type then that is a terrible thing. Yes I hear you re: bird strikes but are we saying that most of the losses were birds being ingested?
I pretty confident that RAF Jaguar combat losses are pretty low so simply shunting 30% is terrible and actually given such a statistic one could argue that an effect defense to RAF air attack would be simply let them fly around long enough and they will crash on their own.
Faced with such losses surely its not unreasonable to suggest that either mission expectations were too high or the aircraft was lacking?
