Jeff,

 

I am not aware of any actual tests = being done. However, Greg Cole worked closely with Andy Chiavetta and Darryl Greenamyer on the modifications that were done to the standard Legacy to = turn it into a Super Legacy.

Hopefully I will remember the pull = the ripcord and deploy the chute!  (:
