We have turbocharged condors here, probably fitted with O2 masks on their beaks, flying above 20,000 feet...
Next you'll be telling me they're IFR rated ?

No actually I read somewhere that the 757's windshield is rated to only 313 knots for birdstrike. That didn't come from John.

As mad scientist notes many aircraft are VMO limited by windscreens.

VD, I understand is the dive speed, but in the case of the 757 this is often quoted as the same as VMO.

I understood that in propellor aircraft VNE was set at 0.9 of VD. Why in a 757 would they be cited as the same ?

Is there an online source to check out V numbers for 757 and 767.

In particular can anyone comment on JL's assertions about wing flutter precluding the B767 attack on WCT2 at 466 knots ?

Anybody care to comment on the alleged "impossibility" of novice pilots diving a 757 at the Pentagon.

I am quite fed up hearing pimple faced kids citing JL as an authority that it couldn't have happened.

I would like to invite the knowledgeable folks here to put these rubbish theories to bed once and for all.
