Navaleye,
You're correct. The RAF F3 had committed and was about to engage when it was hauled off to enable a Saudi F-15 to engage the target for 'political reasons'. I know 2 of the F3 aircrew involved (one of whom is now on E-3Ds) and they were exceptionally frustrated as they were in a far better firing position and then the Saudi almost missed the engagement!!
