NPS, I agree. My dad was an A&P mechanic on 727s. He would go on short hops from Laguardia and JFK to make sure their newly installed engines performed properly. He and the pilots would intentionally kill one of the engines on departure just for fun. This was in the 70s and with no pax aboard. The 727 was a hot rod in it's day.
As for the 757, it has a very high power to weight ratio. It's power to weight ratio is greater than a 777. The one in the video is using Rolls Royce RB211s with almost 50,000 lbs thrust each, and the plane only weighs 110,000 pounds empty.
