Aviation

I saw a top down view of the airport. There are structures everywhere. Absolutely no room for error.
Most airports are like that. Performance numbers are supposed to guarantee terrain clearance in the event of an engine failure, but in this case, it's clear that there was more damage and the crew was doomed.
 
I think this is failed maintenance

horribly failed maintenance

It was obviously a mechanical issue, but it could be a manufacture's defect, a poorly written or documented maintenance procedure, human error, etc. Can't really assign blame at this point, that is what the NTSB will ultimately do.

Yes, but some runways have an extended area (I forget what it's called) that slows down the plane if they overshoot the runway. It looks like a dirt/cement mix that the tires get bogged up within. This runway had no such area. Once you get to V1 you're committed.

That's called EMAS. At V1, you're going flying unless you know for sure the airplane can't fly.

not a new plane so your claim of manufacturer defect does not hold water
and once again how could there be a maintenance procedure that makes a engine fall off?
IF it was a new plane a new type possibly
this is neither
I remember years ago a case where during shift change a forklift was left holding up an engine; and during the delay the hydraulics leaked a little and the engine dropped just enough to damage the wing and that eventually caused a fatal crash

this most likely will be found to be poor maintenance due to incompetence or carelessness

It doesn't matter. Airworthiness directives and service bulletins are released all the time for things that are discovered decades later. In fact, an AD was just issued in January for the MD-11 Fleet for an uncommanded thrust reverser deployment issue.

I won't pretend to know how the engines are fastened to the wing, but there have been issues with faulty parts, faulty procedures, etc, that go undiscovered for years. Alaska 261 crashed because of a combination of these factors. That was on an 8 year old airplane that had logged over 20,000 hours before.

It crashed due to systemic maintenance and oversight failures rather than individual mechanic errors. The airline had extended maintenance intervals and reduced inspections on critical components like the jackscrew to save costs. Both Alaska’s internal quality controls and the FAA’s regulatory oversight failed to catch these lapses.

I say this respectfully, but you don't really have a clue what you are talking about. It could, in fact, be incompetents or carelessness, or a number of other things. This why there are investigations from the NTSB.

UPS has now grounded their entire MD-11 fleet, for what its worth.

I know. I was just asking in regard to this specific situation. Past V1 they had no choice whether or not they thought they could fly. Too many buildings nearby. I was just wondering what if....

I saw an X/Twitter post where someone mentioned it reminded them of the AA crash in late 1970s which I think was the deadliest crash in American aviation history? Engine fell off too on takeoff, and they showed the comparison photo of the rogue engine just sitting by itself on runway. I had to Wiki it to see what happened, but in that case, American Airlines had invented some new repair procedure that bypassed the usual safety procedures on connecting engines. Got it from 100 cables to 30 cables to save time.

I remember going to a party a long time ago, and finding a lot of heavy drug and drinking, and then finding out they all knew each other because they graduated from the same aviation repair trade school. Was funny at the time because I was joking to people I met that I was never going to get on a plane again, but it was bizarre how with mandatory drug tests and all, these guys could live such a play hard lifestyle.
 
human error of one kind or another is what causes virtually all accidents. Micro-bursts, bird strikes, things like that pretty much cover the rest. Its just a matter of figuring out what kind did it. When you have a wing on fire and engines falling off, I think its safe to say the pilots PROBABLY have no blame. Its not new from the factory so doubtful that was a cause. So by process of elimination, baring they find out that a MANPAD shot it down, that leaves maintenance. Or the parts supplier. Counterfeit or faulty parts. It will almost certainly fall into that area; or perhaps both bad maintenance and faulty parts.
 
The FAA has now issued an emergency airworthiness directive grounding the fleet. It could be precautionary (most likely), or they have already determined there is a flaw somewhere (not as likely).
 
I know they can't take chances until they figure this all out. But I would guess this crash has something to do with the plane's stay in San Antonio from Sept. 3rd to Oct. 18th for maintenance. I'm just playing the odds here.

6 weeks of maintenance sounds serious

It's just such a red flag. What did they do in these 6 weeks? Were engines part of it? Wouldn't you check everything in 6 weeks? I have no idea.

low quality or counterfeit parts or a screwup by maintenance

or maybe a combination

that certainly is more than enough time to go through the entire aircraft top to bottom, end to end, wing tip to wingtip.

Latest rumors are that the NTSB are looking real hard at the maintenance logs.

Well of course they are. I'm an X heavy gambler. If I came out of retirement I'd put a boatload on that time it was in San Antonio as the reason for the crash. I could be wrong.

It's pretty routine. They're called heavy checks. Every large transport plane has routine maintenance like this, based on flight time/cycles/months,years, etc. I believe this was a C check.

It could be a number of things, as I have said before: bad procedure, bad parts, careless maintenance, etc. The NTSB will figure it out.
