Back in Feb '09 I was on an air canada flight from YYZ to LGA...very, very windy (gusts up to 70 mph) but planes were still landing. Probably the bumpiest flight I have ever been on. We were on final approach flaps up gear down when we abruptly veered off. I figured we were just going around but instead we flew back to Toronto. This wasn't the scary part though.
Couldn't get out on any other flights that day so I ended up on a 6 am out of Porter. Overnight, a Colgan Air Q400 had gone down near Buffalo, apparently due to ice buildup on the wings. 8 hours later I was on a Q400 in essentially the same conditions and flew close enough to the crash site to see the wreckage. Flight was uneventful, but very unsettling given the similarities of weather and airplane.
