I recall an incident in South Africa (could not find it via google search) where a local TV presenter was not allowed to board his international flight (he may have been late) and decided to block the aircraft by parking his own plane in front of the flight he was not allowed to board.
I think this could have been pre-1998. Cant seem to find it on the inter-web. perhaps some Saffa Rotorheads recall.
Of course I could also be speaking total bollocks, it is early for me.
(TV Presenters name withheld in-case it is bollocks)
