I have to lift you on that one - could you elaborate on which aircraft types?
On the Junglie squadrons, anything engaged is done by squadron aircrew, or the station MTP, with certain maintainers cleared for single engine disengaged runs.
It is worthy of mention, that all of these guys have been working their backsides off (even more than usual) in the run up to and over leave, so well done to all involved!
