"2. The pilots of the A310-300 where amonst the ones with more hours flying this aircraft in TAP Portugal, one of them being the fleet pilot chief."
-Lots of flying hours (lineflying) alone does not make you a good display pilot.
-Chief pilots and other management pilots are more prone to incidents /accidents. This is inherent to their positions, because in them they don't fly much.
- Whatever they practised in the sim, you cannot judge wingtip height in low turns while flying a big airliner.
Even if they (he) were trained display pilots, this was dangerous and unprofessional and in no way will impress real pilots. And no, I am not a mere button pusher
