oberon:
Overstress, yes I agree with you there but this manoeuvre (a loop?) would surely have been along the display line?
As I posted earlier the manouvre was discussed elsewhere, I believe a 1/4 clover was mentioned, I have no idea what AH had planned. But yes, loops are normally flown parallel to the display line, but they don't have to be as long as they don't infringe.
