Pennyroyal - your version of SAR engineering at Valley must be viewed through rose tinted specs because it doesn't match what the rest of the world sees. When you had 7 airframes (and that was only briefly) why was it? Possibly because all the ones you were supposed to fix were still U/S with the flt and the OCU crying out for even one serviceable Sea King.
BTW whose poor availability drags the rest of the SARF down? Oh yes a place in N Wales.
My suggestion to start at Valley is because if the new contractors can make that work, everything else will be easy.
Ironchefflay - the problem with the 139 hasn't been about availability, rather about how it was introduced into service without meeting the spec required for night overwater ops.
