A couple of photos in answer to post no. 482 by

As a young lad watching the helicopters at Battersea Heliport G-AXGO was a very regular visitor. Often a very well dressed pilot would get out once the rotors had slowed sufficiently and then stop them with his brolly.
If my memory serves correctly he also wore a bowler hat ?

G-AXGO Bell 206A was registered to Tradewinds Helicopters Ltd, 24.10.75.
Converted to a Bell 206B II at some stage ? Then crashed into River Severn at Denby Island on 2.3.78

G-BTWA Bell 206B Jetranger II was registered to Charles Hughesden 30.10.78. This was cancelled 25.6.85 and became SX-HBV
Tradewinds Airways also owned another Bell 206A Jetranger G-AXJC but unable to trace any photos ?
