Not operating at Red Arrow standards seems to have been identified as part of the prevailing air display culture. That isn't the fault of any individual pilot. Culture evolves overtime. Hindsight is very good at illustrating how that cultural journey has occurred, it it rather less good at rectifying mistakes made during it. Mistakes that are not the fault of ANY individual pilot, let alone this one flying at a Charity event in an old plane at sleepy old Shoreham.
Consecutive errors, pilot goes into the loop too low being the final piece of the jigsaw. The likelihood & expectation of him rolling out at the top of the loop is being exaggerated in my opinion.
