Sad End For a Beauty
The 720B has always been a favorite for me. My Dad worked for Western Air Lines, and when I was a kid, they were the queens of their fleet. Had 30 or 32 of them, and I rode in them a fair bit on family trips. Only 169 were built, and few people knew the difference from a 707.
I say "Sad end" because, if you search, you can find video of Honeywell scrapping their two (I think) 720s on the ramp, in Phoenix, using a bulldozer. Think it happened last year. Honeywell's airplanes were pristine. Surely they deserved better than that.
They're using a 757 as their testbed now. It may be efficient, but there's no character, ambience, or history.
