You mean the
Chinook that went down, because #2 attacked it? Maybe I missed it, but I don't remember another chopper being downed - at least not one that was mentioned.
The people on Robinns'
Blackhawk were surprised when
Carl took out his Sat; therefore I think these devices are a rare ressource.
Also I remember
Glenn saying something along the line that the sat-phones require to be adjusted to the network they are supposed to work with.
No, I still don't see them sat-phones multiplying everywhere just to open up new story-options.
All the best!
