Three C-17s got me puzzling.
RCH101V, RCH102V, RCH103V. Heading SE from Seattle (McChord AFB) and Frisco (Travis AFB)
RCH### = REACH followed by three digits is common callsign for regular supply flights.
Suffix ' T' eg RCH###T normally indicates a trooping flight, troops on board.
What the hell does 'V' suffix indicate?
