I agree abotu the safety aspect (I spend part of my life as a safety engineer). I'm not sure if the "last minute phone call" was staged or not to provide "drama" for us. But I couldn't believe they were going to shoot an actual person off a treadmill on a moving truck when a weight would serve the same purpose.
Just like the "hanging form a ledge" myth. They could just have a ledge 6' off the ground and puck up their feet, but they decide to go with a 75' building because it would be more "authentic". And it bites them in the behind with a trip to the ER. I thought maybe thye would learn smoething from that, but this proved me wrong.
I realize that most of the dialog on the show is probably scripted anyway, but they also don't do nearly as good of a job at delivery as Adam/Jaime.
