What about health and safety issues?
Surely there must be a point when, no matter how thrilling the spectacle is and no matter how daring the participant may be, the authorities say enough is enough.
Not long since another Stearman crashed in the US with a wingwalker on board and a man fell to his death carrying out a stunt from an aircraft to a helicopter.
Whilst these accidents all occurred in the US, would they (apart from 'normal' wingwalking) be sanctioned by the UK CAA?
