During the mid seventies spare parts for the Gazelles at Soest were hard to come by and as the German police operating Gazelles at Dusseldorf had the same problem spares regularly changed hand attached to crates of beer.
A similar situation occurred in the UK with the Alouette's at Netheravon and Air Gregory at Denham who also operated Alouette's.
All was well until an a new Air Greg pilot was told to pick up some spares from the army.
Sadly he flew to Wallop instead of Netheravon drawing rather a lot of unwelcome attention to the illicit trade in aircraft parts as well as getting arrested.
