Have to agree with Fencehopper here.
Although all my jumping experience is from the UK it was no different there. We had a real mixture at our DZ - all ages and all backgrounds from middle aged company directors, military freefall, Tandem, champion sky surfers to free flyers (guilty), the whole shebang. One thing was a constant though - no one ever f*cked about from the time they got in the a/c to the time they got out of the door......ever!
Obviously I can't vouch for the Fox operation but judging by some of the posts it seems unlikely that 'f*cking about' in the back is to blame - but.
