Not trying to 'two sh!ts ' you Stretchwell, but it could be 3 linked loads. I've tried to erase NVG ULLA from my memory for mental health reasons
I'm fairly certain we dropped 3 lots of 'Blivets' together for the release to service trial. I'll try and dig in the video box-I have film of 3 of us doing the trials. As I remember, 15 ft was the maximum-any higher and the front lip digs in, demonstrated in one of the trials videos. 8- 10 ft was ideal, 5 ft and below got you cuffed by the Eng and you earned the ignominy of a 'touchdown'. I think we got a bit over zealous with the trials and used some iffy DZs-Hullavington was particularly scary-I often wondered what late night drivers made of a blacked out Herc coming over the road at 10 ft.....
I remember being genuinely relieved when I dropped my last NVG Ulla load.
