Well I jump-seated an OPC once (the F/O being OPC'd was a buddy of mine and we had an appointment in the bar to maintain), well we departed NWI, did the single engine and all that stuff, then as we are doing the circuits and bumps back at NWI, Operations (in which I worked), bless them, diverted us to HUY where we ended up arriving back in NWI, as if in disgrace, on the evening Shed360 schedule
But the decent in to HUY was fun, Binbrook kept us high until the last minute before we did a "dirty dive" literally from the overhead down in to HUY ... I was on the jumpseat and my feet were literally up on the "dashboard" whilst trying to hold on
