That sounds weird, i mean you could say that they where just getting deliveries, but why the high security ?
I take it you cant see the runway from where you were, otherwise you would have seen the different planes stop and pull off the runway?
It sounds like they where using the touch and go training to allow these planes to land without people noticing? a plane would land, and a second
plane would take off and do a loop? couldnt you see more than one plane in the sky at the same time?




It doesn't make me impolite though. I do accept your thanks and you are welcome.
