If the ditching was controlled and the weather/sea state were epic then how come a navy helo with flotation gear attached sunk?
Known Lynx ditching characteristics I’m afraid. The aircraft had a seriously expensive MOD package during the 1980’s to increase the number of Flot bags from 2 upto 4. This has allowed the average crew an extra 15 seconds to abandon the aircraft before its on its way down to Davy’s. This aircraft apparently sank in 45 seconds.
