The presence of a camera changes pilot behavior. Truth. Hangies call it Kodak courage, skydiving has had lots of video cameras as training(and ego) tools since the big old expensive VHS camera days the danger is well known. Not saying don't do it, just saying there is a pile of bodies from camera related behavior changes and we need to be vigilant about the effect of having cameras on board, or pointing at us from the ground. Fun little experiment, get a big camera(doesn't have to work) and tripod have a friend set it up away from where gliders usually roll out and watch where pilots land. Like moths to a flame...
