I wondered if it was one of those "viral" videos, but then I thought, GoPro has plenty of much better videos to show off their cameras.
Wingsuit Flying: Reality Of Human Flight (skip the ad, video worth watching, but also shows why wingsuit flying is the most dangerous form of skydiving/base jumping there is and why so many participants die)
Experience Zero Gravity
Those videos would sell a camera much better than a seagull. If I were a younger man and had no family...some of that wingsuit stuff would tempt me.
...wingsuit flying is the most dangerous form of skydiving/base jumping there is... Yeah, but I'll bet SpecOps is all over this. Imagine an insertion miles away, no chute except at the last second, after flying for how many miles through canyons to get somewhere under radar.
Of course, I can't see all that much equipment being carried, and flying at night would be out (unless night vision was used... hmmm...). But still, for military forces who live on the edge, I highly doubt this hasn't been investigated.
