TOFO,
You say:
"for MR2 add on 1 dry man."
Do you mean that the MR2 crew is as for MR1, plus one extra Dry man, or do you mean that the MR2 crew is as described on the RAF website (below), plus one dry?
"two pilots and a flight engineer, two weapon systems officers (WSO) (tactical and routine), and a WSO who is the sensor and communications coordinator. He is, in turn, supported by a team of two ‘wet’ weapon systems operators (WSOps) and four ‘dry’ WSOps."
Jacko,
MR2 Originally the former; currently, go with the website. They seem to have dropped a wettie, somewhere along the way. After my time. I guess, sorry for the confusion.
