Here's the other picture I have of me in Grasshopper XP490 (date confirmed from my log book as 22 May 1980, 3 'flights' that day, total time 1 minute!).
This picture was taken by Don Stanley, our Tech Drawing teacher and amateur photographer who wanted an action shot and positioned himself in front of me in the V of the bungee....
Note duty cadet in the background with the garden fork from which the machine was tethered as the bungee was stretched. I appear to be looking down waiting for the bungee ring to release. Damn smart beret though....
