A few days before my retirement in 2004....My son Ryan and I were invited over to the
Boeing Delivery Center's 777 Flight simulator for lessons from the test director.
I crashed a few times when trying to Tex Johnston barrel rolls. It didn't like my vertical climb into a tail-slide...(crashed really bad...straight nose dive into Lake Wa.)
Ryan did extremely well and flew not one but two barrel roll with no changes in gravity. He wouldn't have spilled a drop of water from that infamous water glass of Tex's!!
However on the third roll.....the Boeing Simulator Computer system crashed and had to be
"rebooted!" It took the flight simulator crew about 2 hrs. to get back up and running again.
Geee?
We haven't been invited back to fly the new 787 Screamliner??? Wonder why?
