Kengineer-130,
I couldn't find the video you referred to but I thought you might like this one made by the RAF Museum - it includes several people giving first hand accounts from the earliest days in RAF service. I wasn't aware of the JATFOR exercises referred to which involved 36 x C-130K flying low in close formation - must have been impressive.
