Holding on the ground, 35mins, holding overhead Lee Point 30mins so far... its freaking annoying, specially when the trainee ATCs are on and your pulling hair waiting at the holding point for a 210 on 5mile final.... whats everyone elses records?
But yes, watching the F16s and F18s peeling over head is very cool and when they take off as your at V2 is especially noisy and fun!
