Back in the days when we had an air force, there were quite a number of these communications squadrons. They flew from stations such as Andover, Bovingdon and Topcliffe (2 of which have since been pongo'd, the other is a prison) and would potter about the UK in Ansons, Bassetts, Devons, Pembrokes etc. carrying scrambled egg-hatted officers about. They went about their business in a quietly, professional manner until the axe-wielding bean counters decided that they had to go....
The last remaining comms squadron is 32 at Northolt - 4 x 146 and 2 x 125 plus a couple of helicopters......
And nowadays senior officers aren't even entitled to first class rail travel.
