Biggus - the F35 basing study indeed rejected Kinloss due to single engine v's geese concerns, hence F35 to Lossie and Tonka to Kinloss was the plan from 2013 (The MRA4 basing at Kinloss was only guaranteed to 2013 - Burridge's grand plan was to concentrate all the ISTAR at Waddington after that).
P8 manning is 2 WSO & 4 WSOp per crew I believe. Reaper crews have either 1 WSO or WSOP, but WSO's are in the majority.
