RAFG FGR2
Of course the RAFG FGR2 were the elite force hence the 5 minute readiness - actually the job was easier than UKADR FGR2s which had a much bigger airspace to engage targets - The RAFG F4s on Battle Flight adopted the following procedure- THe aircraft was winched back into the HAS and the backseater re aligned the INAS and made a note of the heading which was then written in china graph on the instrument panel - this fast align method took the stored heading as its reference hence the 100 second align as opposed to the 10 minutes. The aircraft was connected to ground power 24/7 which kept the INAS heaters on and hence the oil warm to aid erection !
Thanks for the tips Courtney - the film is about 1988 vintage so probably fogged
