Gentlemen
One thing you can't forget even with the catch net set up somewhere in the area
prior to the dyke it still takes a lot of space to deploy both chutes coming 
out of
the retainers plus the slow down of the vehicle. I know its not the only thing 
to
look at but must be considered as part of the the deal. Also if a vehicle did 
not
get the net in the center but closer to one side the total effect will change in
the deployment process. Lots of things to think of, gads it late in the day and 
I'm
still trying to think.
