interesting approaches....nothing quite as geographically challenging as some of the above mentioned....but, while flying for the UN in the congo, in the jungle on a short final, there was an antanov 24 on a short final from the other end...if anyone has flown with russians in the area you will know that playing chicken with them is not cool! anyway, we touched down first...kept power in case we had to do a touch and go, he finally went around about 20' above us and when he had finally shut down, myself and my fellow pilot thought we would ask him if he was monitoring our radio transmissions...as the back of the an 24 came down and a 100 governmnet troops marched out we thought...nope, he can do what ever he wants...we're out of here!
