Knowing, from the lectures at Seafield Park, that you were supposed to wait until all movement ceases before making your way out, it was mildly concerning (to say the least) when we made our way to the tower and I thought the Dunker had to get all the way to the bottom before we could get out. It wasn't until we got to the top and into that horrible little shack that I realised it had a false floor. After that it was okay
One of my mates on our course managed to get his helmet caught among the seats/straps. When the divers brought it out to him the chin strap was still done up and, try as he might, he could not replicate getting out of the helmet without undoing the strap. Wonderful stuff adrenaline.
The Yeovilton Dunker was so much more civilised, especially for VL-based aircrew
