Not a PMDG specific topic, but since PMDG have the best 777 on the market, I wanted to ask here as I don't frequent any other forums - sim or real. A report released here in Australia regarding missing flight MH370 says that data collected shows a descent rate of 20,000ft per minute. I was just wondering if any real-world 777 drivers here can say if that's really possible, because I'd have thought a descent rate that fast would surely have to break Mach 1 and rip the wings from the plane with the aircraft crashing into the ocean with so much speed as to entirely obliterate it.
