At a Biggin Air Fair - I think it was '70 or '71. NB flew his 'usual' inverted Zlin at around 50' almost OVER the leading edge of the crowd line! Very, very dangerous. That, is how I remember him. How he died is how he was bound to die.
Dying while doing aerobatics at age 71 is not such a bad way for a pilot to go.
As I recall, Neville was a member of the Black Cat club which was an unofficial (and unapproved) sub-section of the Tiger Club - for those who had survived the total destruction of an aircraft. One of the clauses of its constitution was that,at the discretion of the committee, posthumous applications for membership might be entertained.
And, yes, he was a gentleman.
