Many thanks for the replies - even those questioning my sanity!
I did a 'bush flying' course with CC Pocock in South Africa last year and it was brill. He's a bit of a maverick but I learned so much in a just a few short hours, at the end of which I could easily land a C172 in less than 150 metres (mind you CC could do it in about 75
)
If I manage to get anything organised for this trip, I'll let you know
Cheers,
Tony
