I've had it ring at 2500'agl at which point I told whoever (my wife
and curtly too) that I was busy flying and then shut it off (I forgot
to shut it off prior to launch). If many consider it unsafe to drive
and talk, why do it in the air?


First, there are hundreds of thousands of pilots trained to verbally copy
and read back complicated airtraffic clearances while flying extremely
complex aircraft. For these pilots, a duplex phome conversation while
flying a simple glider is childs play. However, if it bothers you, don't do
it.

BTW, I don't think using satellite phones aboard an aircraft is prohibited
by FCC regulations.
