On his point about airline pilot training, a friend of mine is a retired airline pilot and he said the skill level of newer pilots was already suffering when he left a few years ago. Some of the newer copilots could not land a plane under certain conditions even after a few years in the copilot seat. If the main pilot had a medical issue the copilot would probably crash the plane during the landing. They somehow were not getting the experience to handle those tough routine landings. If new pilot training is getting worse I would expect botched landings on certain runways, or under conditions like cross winds. The landing is—by far—the hardest part of the job.
