Thanks for the replies, but we did the flight last night in the Training Arena and had a fairly good turnout. I tried calling Hitech but never got an answer on the phone, it went straight to voice mail, and he never called back. We would have used AvA but tank wars was already there.
Bottom line though, was it was really to short a notice. IMHO a memorial flight, should take place After the funeral, and have at least a week to plan and alert other players of the planned flight.
