Boessi - thanks for the clarification of terms but the same factors are valid, the aircraft has to be airworthy and someone has to take the risk.
The Sea Kings were taken out of service partly because of the of the costs in manpower and spares in keeping them serviceable and, unless they have undergone a Carson style rebuild, they are they same rattly, leaky, ancient machines that I know and love but am quite happy not to be flying (especially in an overwater role) any more.
VRS failure at night in the hover/dip anyone?
