With over 35 years in the manufacturing environment I'm sorry to say I've seen variations on all of those themes...except the last one.ush:
An acquaintance of mine was a mechanic for Korean Airlines at Los Angeles International Airport at the time. (In the Air Force he married a Thai woman and that's why I became acquainted with him through my Thai wife.)
A Korean 747 air freighter arrived at Los Angeles International with a zero time 747 Rolls Royce engine on board ($$$$$$$). The Korean workers sent a fork lift out to pick the engine out of the side cargo hole of the freighter. Forget the exact numbers here...but let's say the engine weighed 14,000 pounds..the forklift was rated at 12,000 pounds of lift. The Korean ground crew knew the forklift would lift much more than 12,000 pounds. They used this forklift to pick up the 14,000 pound engine. They backed away from the freighter with the forklift up in the air and with the 14,000 pound engine high up in the air on the forklift. The Korean forklift driver backed up, turned around and proceeded forward, and then braked..the forklift tilted forward and dropped the 14,000 pound zero time Rolls Royce engine on the ground. It turns out that the 12,000 pound limit on the fork lift was not based on its lifting capability...it was based on a center of gravity consideration where if in forward motion, a sudden brief braking, would cause the fork lift to tilt over! The Koreans were oblivious to the center of gravity issue.
This same acquaintance had a lot of scary stories to tell about Korean Airline pilots. As you can tell reading the Asiana Airline crash...they are a different breed.
First rule of load carrying with a forklift: Get the load as close to the ground as possible whenever movingAn acquaintance of mine was a mechanic for Korean Airlines at Los Angeles International Airport at the time.

Early/Mid 80's I built a machine that inspected the first stage compressor/intake fan on them Rolls engines...RB211, bet that Titanium did not appreciate the sudden stop on the pavement.....I suspect my machine would not be needed, ya THINK??
:surrender:
Remember years ago when a DC10 tail engine exploded, severed all triple redundant hydraulic line..the flight crew had no aileron control, no rudder control, only elevator trim tab control, no flaps...etc. DC10 instructor trainer was on board. Using left and right engine power, the crew was able to steer the aircraft. By using power, they could control pitch somewhat. The flight crew and the instructor were able to crash land the airplane so that about 2/3 of the passengers lived.
The reason for the engine explosion was that a large diameter titanium rotor in the center engine developed a hairline crack and then the rotor shattered.
I'd guess your inspection tool could have saved the day if used?
I flew on DC-10's and my experience was really favorable. Liked the piano bar and lounge they had on the international flights. Really nice to walk around with a drink in your hand. But, there were a lot of just terrible DC-10 accidents. Douglas Aircraft was skating on bankruptcy when the DC-10's were in flight test...I think they cut a lot of corners and made some design expediencies just to get them certified. Because of their accidents, and flight reliability problems, I understand that airline pilots were ultimately refusing to fly them.
when i was in high school i worked at a lowes lumber yard and drove a forklift, never had a serious problem . i did have a case where a guy loaded a pickup with lumber and one of the sales guys came running out yelling at everyone, i chased the guy to the second traffic light and lifted the rear end of his truck off the ground a virginia state trooper happened by , pulled up behind me and was laughing so hard he couldn't talk. he motioned the guy out of his truck. after that every trooper that came thru would ask me hey are you the guy.....:thankyou:

The company started out as the distributor for a European (Finland?) mining company, maybe mining gear Outtokumpu ?? sp?? and so INTEX of Bethesda Md. was the importer that got their mineral/mining gear they used to find ore deposits with, modified and FAA certified for use in detecting moving metal, on a walk through archway basis, the early ones were A framed shaped and ran on the standard RF, looking for de tuning of the signals by the test 'standard' which BTW was a 4" piece of 1/2" diameter steel bar, figgering on seeing/detecting any part of the smallest automatic pistol made.....certainly the FRAME at any rate....
SO, being as our customers were airlines, one of the companies we bought out was into checking the RB211 engines first stage compressor...that huge 6' diameter fan you looking at on the intake.....it was a strange sort of construction in that the hub was about 2' diamater and a foot thick, all the bolts onto the shaft like a car wheel setup....well off this hub was all the blades fitted into a compound slot we called the 'Christmas Tree', so imagine a tree with all it's branches that fits into a form so that all the branches and engaged and the trunk of the tree can not pull out of there, being held by the branches....the fan blades were about 3' long and 5" wide, and of course a compound curve that made inspections difficult and LONG time wasted with dye penetrate took about a week+ to do one engine....
Our machine could inspect for stress cracks down to BCH level and done in a day or less.....it had automated probes wound on a copper and ferrite construction with a tip of ferrite we made under a microscope, Debbie was GREAT at that shit, she could turn out them coils just perfect, she was the lead assembler on small shit in the electronics, good eyes, tiny fingers, and smart as a whip too, tell her once, and fuggetaboutit, no reason to waste time hovering.....:loveletter:
so the motorized test mechanisms I had to build from a stack of D size drawings about 3" thick, I remember walking into the Don, the M/E's office one Monday AM and so setting down, and asking 'SuPP??'
He leans back with his own coffee cup and grins, 'Have I got a PROJECT for YOU!!!! you got 6 months to do it'.....:surrender:
so Debbi and I assembled, tested, this automated machinery capable of following the compound blade curves, and all aspects of the 'christmas tree' set up on the hub/blades......AS I RECALL, from just visual looking the standard was like 1/8" of visual crack was max allowed.....
We took some of the electronics and came up with out own probes for testing heat exchangers in Nuclear Power plants....you know, water to water from the nuclear pile to the water that ran the turbines....those had to have NO LEAKS, well no shit....:surrender::twitch: OUR gear could pick it apart, no one else had the tech.....
There was one app for the gear that we changed the operational theory from using RF to using pulse field as with our own line of walk through metal detectors, funny thing the other day I spotted some new shot on TV, and there was one of our metal detectors still on duty at some courthouse, 30 years later....go figger.....I recognized the formica/oak finish archway in a nanosecond.....:smash:
