G-SPEY wasn't the Castle Air B206 "Lost at Sea", she's still going strong still with Castle Air. She's joined the company in 1982, was sold in 2004 only to bought back in 2008
It was the actual star of 'Treasure Hunt' G-BHXU that ditched off Alderney on 29.6.95 piloted by Michael Malric-Smith, en-route Liskeard-Deauville. The engine gear box packed & engine stopped 17 miles from Alderney at 1000ft. Michael carried out engine off landing & ditched in sea - aircraft rolled over and started to sink in about one second. Escaped under water using short term air supply system (STASS) (first time used by civilian crew in anger). 2 crew Picked up by Navy about 45 mins later and flown to Guernsey, then back to base with Keith in G-TELY. Rigged the spare (G-SPEY) left at dawn the next day to France and completed job on time. G-BHXU sank & was not recovered.
Speaking of Green & Gold helicopters... my first experience of the B206 was in the green and gold G-BALC of Pork Farms - almost exactly the same colours as one of their Pork Pies. We were treated to a low level flight across flooded fields around Gloucester after completing a compass swing at Staverton one Saturday morning in 1977.
I don't suppose any one has any photographs of G-BALC in her Pork Farm livery?
