Nice photo Peter. I notice the C-118 and C-47 in background. Were these Belgian Air Force aeroplanes?

Good evening VeeOne,

Yes, the aircraft seen on the north side of Brussels airport were Belgian Air Force planes. That side still is the military part of the airport and is called Melsbroek, home of the transport aircraft of the Belgian Air Force (C-130 Hercules, Airbus A310/A340, Embraers 135/145 and some bizjets). The aircraft seen in the photo are C-47 Dakotas and Fairchild C-119 Flying Boxcars of which they had quite a few at the time.
This is one of the C-119Gs present that day:

Kind regards,

Peter
