Two instances of aircraft emergency that occurred to me come to mind...............well three actually.

The first was when I was on a USAF MAC flight in a C-130 from Incirlik to Izmir, Turkey. The cabin suffered explosive decompression and the flight crew initiated a screaming dive to 10,000 feet. No oxygen masks hence the over rapid descent. It took two weeks for my sinuses to catch up.

The second was when I was flying a friends Cessna 210 Centurion from Wichita where it had been re-engined to Manassas, VA. At 8,000 feet while descending and ten miles from my destination, the engine seized. I dead sticked it to my destination. Then suffered a case of the uncontrollable shakes for hours afterwards. The owner had a new oil Phillips X/C II oil that was later recalled because it was turning to sludge and locking engines. Phillips paid for a new engine.

The third was while departing McCarren International Airport in Vegas following the SHOT Show, the right engine in my T-310 suffered catastrophic failure at rotation. Turns out the crank, which I had replaced by Continental, was from a bad batch. The metallurgy was goofed up. Continental replaced the engine under warranty. Another bad case of the shakes.
