Short answers to the above....
Bravo 73... The museum couldn't justify flying a Sea King unless it had a duplicate and in any case the engines are likely to be removed by MoD due to their spares value. Knowing the challenge faced by others to get an ex military Wessex past the CAA,I hate to think what the reaction and costs would be to get a Sea King authorised,even with AW backing.
3D Cam....the museum did approach Bristow but the U.S. Owners decided they were too valuable .I believe the last ones are now in the USA.
