i was there with him talkin him thru that landing... he has landed many times and they are almost as good as mine most of the time. but this was not a hard hit .. it was his intent on pointing out something and not to get chastised for it.... i have flown enough planes in my time (8yrs) to know a few things.. and this shouldnt have happened with this incident. there is clearly a minor problem that we observed and felt the need to address... and by the way he is a good pilot... and does very well for just starting out in this business. and, as i said, was just pointing out a flaw to others that may be getting this airplane.
