For the record the boys in Fox were not 'wayward, ill-disciplined yahoos'
the owner operator was in his 50's, his best mate was in his 60's the other two jumpers were old enough to have got through the yahoo stage. They had run a very professional outfit for a long time. They were good experienced tandem jumpers and I can promise you they would not have been larking about in the back of that a/c. Its pretty obvious that it was out of CoG and very much so, and the emergency AD indicates that with 8 pax the margins are slim or non-existant.
In my opinion if the emergency AD becomes a permanent thing then whoever certified that mod for 8 people is at fault right from the get go.
