One technician told me the same story about Lossiemouth with those small pop-up toys with the spring and suckers. On the final day of training the standard practice was to place one or more of those just behind a cliff edge. When the pilot flew 300 feet over the tree line and dropped down, that was the first thing he'd see. Bonus points if the toy jumped into the air at that moment. I can only imagine what one of the toys must have looked like when scaled up.
