This thread could become the longest and most posts ever. As much as we have been on airplanes, I am sure most all of us have experienced something weird.
Aborted takeoff: Tampa International-rolling down the runway, almost at "rotate" and there is a LOUD BOOM from the left engine on a DC9, brakes, the lunge forward, the stop, the taxi back to the gate and the brief explanation of a "minor problem" (seems there never is a MAJOR problem). Passengers allowed to deplane and wait in gate area. I, with my trusty carryon, go to the gate agent and retrieve my ticket to DCA, then look at my OAG and see that another flight is leaving in 45 minutes. I go to the gate, get on the flight and land at DCA about an hour after my previous schedule.
Aborted Landing: IAH-CO, Descended out of the clouds, looked down and saw we were about halfway down the runway and still a few hundred feet off the ground. Engines roar and the nose points upward and we make another pass and land successfully.
Severe Turbulence: DFW-IAH, CO, at cruising altitude, FA's have cart about midplane, sudden HUGE DROP occurs, everyone's drinks, the drinks on the cart (coffee & all) go flying through the cabin, my seatbelt buckled loosely and I nearly hit the bottom of the overhead (make mental note to always fasten seat belt low and TIGHT). Besides a huge mess and some soiled clothes, no one was hurt, just scared. FA's hand out vouchers for cleaning, I opted to take a bottle of wine instead of the voucher. The rest of the story is uneventful as all went well.
So, that's my most memorable "near misses". I surely aspire that this is all that I ever experience.
