airclues - why do you ask? I have never found it too much of a problem getting into 21 however take off needs a little more care with fairly tall trees to be crossed on climb out (alternatively if you have sufficient height and speed a gentle turn to carry on the climb down the 26 axis is helpful). I remember watching a Rallye 100 going over the trees this Autumn - it looked very close and the a/c did not reappear until it had turned left away from the circuit - it looked as if it was going back in ground effect!
