I have flown to and from Japan and all over the the US, but the single scariest flight i have ever been on was just 2 weeks ago. Flying into Denver from LaGuardia. They deliberately changed our flight path to avoid some weather, so we had been in the air for about 6 hours. Flight attendant gets on the PA and informs us to buckle in as we are about to hit a "rough patch". No more than three minutes later, maybe it was a microburst, the plane goes into free fall. We go weightless for a short time. Once the plane is leveled out, we get diverted to Fort Collins for "refueling". After we land, two sets of EMT's board to check on everyone. Two of the flight attendants are carried out on stretchers and sent to the ER. Per FAA regulations, we can't fly with only two attendants, so the airline shuttled us to DIA.
I am done flying for awhile.
