I gotta agree with some people. These guys clearly need some work on there rappelling, it's obvious they have had some instruction and SOME practice, but not much and by the looks of there speed not enough. I would be surprised if they had performed the actual act of rappelling out of a helicopter more than 10 times, and they certainly don't appear to be practicing as regularly as they need to remain confident in there ability. As stated earlier, when rappelling out of a helicopter there is a moment of commitment where if you hesitate you swing back in and break your jaw/face on the strut.
In the field I work in, I repel quite regularly, sometimes daily for weeks at a time. I have been doing this for close to 8 years, mind you off of buildings and stationary objects, not a moving helicopter. In no way do I think I could just jump out of a helicopter and do what these guys are doing and look as professional as they do. However, there repelling skill and knowledge of rope, and harness is clearly lacking from what I would think "special forces" would be trained in and capable of.
I think they look like they know what there doing, but my guess is they just don't get much opportunity to practice it. It's a shame, because with practice they look like they could be elite. I would expect more from Canada's best.
