Pilots tend to be obsessed about handling skills, the majority of jet transport accidents arnt caused directly by lack of handling skills, they are caused by error chain human factors
Neil Williams was an excellent handling pilot and an aerobatic champion but he killed himself and his wife by flying below safety altitude. A PPL with 5 hours solo could have prevented the accident.
At Kegworth some of the passengers with no flying skills where more aware of what was happening that the two pilots.
At Staines none of the four pilots realised the aircraft was stalled.
Improving the handling skills of any of the above accidents wouldn't have prevented these accidents
