Hi Sid.
From your profile you seem like an accomplished guy.
I detect some undertones of disbelief regarding Dennis and his scholarship.
Sir, if that is the case, you are sorely wrong and you clearly don't know (which is very rare in the heli world) Dennis.
I suggest you telephone Dennis at his office at Shoreham Airport, West Sussex.
He will happily and selflessly allay any doubts you have.
Kevin.
