Back in the late '80s when there were a ton of regionals flying turboprops, I recall some interesting flights. ASA used to have a big fleet of Brasilias that they flew to feed traffic to ATL. They had a flight that left HSV at 0530. I took that flight several times so I could be in HOU by 1000 for a mid-day meeting.
That flight was never full and sometimes everyone got a little silly on account of the early hour. Those Brasilias were way, way overpowered for their size (had to be to guarantee that they could fly on one engine). Got on the 0530 one morning and there were only about eight pax. FA told jokes over the PA as we taxiied out. At the threshold, the captain applied brakes and then firewalled the throttles. When the brakes were released, that Brasilia shot off the runway like it had been fired out of a cannon! We were turning for ATL before we'd traversed half the length of the runway.
The only really scary moment I've ever had on a flight was on a DL MD80 landing at DFW a long time ago, circa 1990. We came in just ahead of a front. On landing, just as the main gear touched, we suddenly got a huge cross wind. The aircraft went way over to the right edge of the runway, and then the left wing lifted and I watched out the window as the right wing tip came to within about two feet of the dirt next to the runway. Fortunately the flight crew was on the ball and they recovered it. Last year, during an approach to ATL in an MD80 (Delta, when are you finally going to get rid of those things?), we hit some wake turbulence. I've never experienced that before. It wasn't really scary, more of a "hmm, that was different" moment. The A/C rolled left pretty sharply for a moment, nosed down, bobbed around for a moment, and then recovered. I knew it wasn't plain old air turbulence, but I didn't know what it was until the captain announced that we'd had a wake encounter. Other than the weird sensation, the main thing I recall was the toilet seat in the head banging around...
