Course I do!
As a Strike Sight King I used to calibrate the weapons system. The Buccanneer had a couple of modes one called dive bombing the other A.D.S.L. (Automatic Depressed Sight Line) ADSL was simi;ar to dive bombing but instead of diving in a straight line the computer generated a sight target which caused the pilot to dive in an arc rather than straight line as in dive bombing. This suppossedly made i more difficult for enemy radar to lock onto the aircraft. Both of these modes used degrees od depression ,i.e. 4degree dive bombing 5 degree dive bombing etcetera. Now some boffin decided that if for some reason the strike sight system failed an attack could still be carried out visually by using markings on the flight refuelling probe. These were marked out using the strike sight telescope (scouse will remember it well) to align the marks with certain degrees of depression (I forget the numbers now cos me brain id old and fuddled).
Mk1 the days of no inflight refuelling probe!! deliver bombs in a 20 degree dive to within 20 yards. In the Mk2 SIR never selected his master armament switch to ADSL until he was steady in a dive, in order to preclude "premature" release of his bombs as he rolled into the dive
