Hi Ed, KL7UW
Your proposal (ARISS on ISS) is so clear that I cannot understand
why some AMSAT, VP Engineers do not completely agree with you.
Following their answere to you they seems to be more lawyers than
You are right Ed when you writes..............
"If Fox or P3E sit on the shelf for 5-10 years for lack of a launch
maybe better redirected for ISS. Not my call, obviously."
PS: some of us are getting old and may not still be here in 10-years?
