Macho bulls@@t stunt flying. Impressive to look at but would have been a whole lot different with an engine out or a blown tyre after V1. I wonder what the second segment climb profile would have looked from this airport (6500' amsl)?
The reason that this flight couldn't have taken place under public transport regulations is that there were unacceptable safety margins to satisfy the duty of care requirements for fare-paying passengers. Captain, what about your duty of care to the Boss in the back, his or her oblivious colleagues and your starry-eyed FO?
I sincerely hope that this was an owner pilot on a solo jolly and not a professional crew with passengers on board. If it was a professional crew then I implore the FO to read the sorry tale of VP-BAF at Samedan and get away from this operation before that Captain kills you.
