Boeing 707 performing a barrell roll..

This is the video of the Boeing 707 test aircraft (known as the 367-80) performing a barrell roll during a display flight in Seattle 1955! Amazing to see such a large airliner perform this maneuver. Concorde also performed barrel rolls during it's testing phase and was quoted as being "reguraly rolled by it's French and English test pilots". Not only is this amazing it also begs the question, what is the feasibility these sort of maneuvers in commercial aircraft. Barrel rolls produce very little in the way of extra load usually as little as 1-1.5 g which can be less than a 60 degree banked turn, but what about other aerobatic manuevers?
