William Seger - Epic Fail

[William Seger]

24. "Getting somewhere," huh

> So Seger, based on your conversation with the FAA via email, what is the "margin of safety" past Vd based on FAR 25.301, 303, and 305??

NOBODY KNOWS, Balsamo, and that's the whole point -- the whole reason your "impossible speed" claims are bullshit. Nobody knows because the only way to find out is the hard way. However, what we do know is, if the engineers accurately estimated the airframe stresses and then applied a 1.5 factor of safety to those stresses -- as they are required to do by the FAA -- then there certainly is a "realized margin of safety" if you should happen to find yourself flying faster than Vd. The reason for the factor of safety is that when you do the design, you can only estimate the real-world stresses and structural strengths, and if you're going to send millions of people up in the things, you damn well better be sure you compensate for any possible bad estimates.

Out here in the real world, we don't know the actual limits of 757s and 767s, but we do know they weren't reached on 9/11. You're trying to tell us that we were deceived, and my question to you is, why are you pretending to know what speeds are "impossible" when you don't have a clue how airplanes are designed?
