Ex-forces and ex-airline pilots in the biz jet world generally were far better pilots/operators than those without that experience. Obviously there were exceptions, but that was my experience.
One did not have to join the airlines or the forces.
Some of us could recognise the "cowboys" while we were still flying C182s and Barons before climbing the ladder to corporate jets.
Tragically, most of the "cowboys" did not survive to climb the ladder to corporate jets.
I note in the video that he/she started rolling before climbing from the low pass. Best way to end up cartwheeling down the runway.
One of the closes call I have witnessed was two airforce transport aircraft depart in formation, They were on each side of the runway for the take-off roll in trail. As they both lifted off and raised the gear, the first aircraft turned across in front the second aircraft to "beatup" the gingerbeers. This caused the second aircraft to descend extremely close to the ground which by this stage was also heading towards the gingerbeers.
Being in the forces did not automatically give you discipline.
