Berlin corridor
Best I can offer is having been on 60 Sqd at Wildenrath 1969-70 up & down the corridor in & out of Gatow & Templehoff with our camera equipped Pembrokes (they did exist, quite clandestine those days !), often spent time comparing notes with US Herk crews about what we had seen on the ground & what to look out for, don't remember them being other than normal camo & markings though, but some years ago ?, ah happy days, Paul H.
