Reminds me of the May 25, 1979 crash of AA Flight 191, at Chicago’s O’Hare Int Airport. Damn near identical scenario where the number one engine separated from the wing. MX crews were using a forklift to mate the engine to the pylon. They overstressed and cracked to engine mount bolts.
I witnessed some geniuses doing the same thing on a B-707 cargo conversion, in 1986, at Batch Air in Miami. These Cuban idiots had the engine pylon resting on some wood planks that were laid atop a 10’ step ladder, while the engine was being overhauled!
