While it is possible to do these types of manuevers in a transport type aircraft, not all pilots will be able to pull it off and will leave a smoking hole in the ground. Sucks for the pilot that dies, but it is criminal for the people that are riding along and get unwillingly sent to an early grave. If you want to roll an airplane, go rent an aerobatic airplane, put on a chute and have a blast. And as an FTU instructor, I will tell you that the principles that should have been learned at UPT are not always remembered. Performing acro in a T-6 or T-37 6-9 years prior does not translate very well into being able to fly aerobatics in a MC-12 or C-130 etc.
