On our Graduate Entry course at RAFC, one chap broke an ankle not long before he was due to take his FHT.
So The System decided to take 2 grad photos; one included him (with his plaster cast carefully concealed) while the other did not - in case he bonged his trip.
We took rather a dim view of this, so the 'without' photo had people holding hands, pulling silly faces, picking their noses, flies unzipped etc. and could never have been used. Fortunately he passed his FHT and the final grad photo was fine!
