I can smell this video of the Aviation Fuel. What a wonderful day and evening it looked like to plane spot. I love these archive videos from long gone aircraft, airlines, and in this case Stapleton International as a whole. Thank you so much for posting this. Absolutely incredible footage!
The irony is that United had the B-Concourse on DIA originally built to cater towards the 737. Yet here we are in 2019 and the 757s / 767's have begun to creep back in more and more. United is rumored to be moving their HQ to Denver. As they are expanding B-Concourse.
