May be type rated training brought into question. Normally to fly different aircraft professionally you are required to be type rated on them. So you get your license to fly but type rating is like what aircraft you can fly. So its possible that has been brought into question. That being said pilot training is always brought into question in every crash as most crashes are pilot error.One of the crew confirmed as dead. Scottish Police won't say who.
Pilot training has been called into question, given that many pilots are ex forces I can't see how pilot training can be blamed.
