Occasionally huge discrepancy between external view and cockpit view:

when I sit in my cockpit I fly around as usual. When I switch to external view it happened to me once that I no longer could control the aircraft and it behaved as if autopilot was switched on (it wasn't).

Also on this occasion I had my engine badly damaged and it only turned through wind. In external view it was still running (though not well) and I would bet that I even got some thrust from it ...
