Has anyone looked at the maps etc and considered this?
The aerobatic bit was carried out over the open land to the north of the airfield (low risk).
On exiting the move there is obviously a problem and he is trying to make it across the A27 to the clear ground to the West of the airfield.
Whatever went wrong though, due to the kink in the A27 at the point of impact, meant he was over the top of the road for a short period of time rather than crossing it at 90 degrees.
Unfortunately cars were queuing at the traffic lights at that time. The Vauxhall helicopter incident two years ago could have been so similar to this had the traffic lights been green instead of red.
RIP to those who were caught up.
