On the subject of perf, you should have tried a two-engine ferry. Now that was an interesting take-off. There was a period of about 20 seconds from V1, during which an engine failure would result in the Airways Pension Scheme having three fewer monthly cheques to write in the future.
It was volunteer only, and we received a very nice commemorative tie for doing it - a three-pronged trident (as in Neptune's), with flames burning from only two spikes.
The trip was MAN-LHR, with a T/C with initials VG. Didn't phase him at all, as he'd done several already. The perf calcs took forever.
Still got the tie and, now, the pension too.
