Ok.. so not quite an Aer Arann ...
Happy Christmas to you all
RadarBox uses the first 3 letters of the Flight ID to display the Airline Logo
REA = Aer Aronn
REACH = US Military Air Command - or on contract to the same.
Much the same way that RAF Tankers, TARTN display the TAR airline logo
No way around this really.
The crews normally put RCH in for REACH, which means you can have a mil logo RCH showing :-)
