I think we all understand that nose down inputs in the flare are potentially dangerous,
but I would like to again remind of the possibility of large scale chaotic turbulent flows from the adjacent terrain significantly interfering with the flare. I agree that it did not seem to be a good day to be landing at Aspen.
I haven't flown into Aspen enough to be able to characterize the turbulence possibilities, but the flare portion of the video is so busy/unstable that it seems to indicate the presence of significant turbulence. (Lets just say that it put me in mind of one of my prior experiences that resulted in a diversion.)
Perhaps some of those with a lot of trips into Aspen would care to comment on the turbulence possibilities.
