I'm not really sure, having flown nothing larger/more complex than a Seneca myself. The only things that come to mind immediately are dropping below Vmc with an engine failure (real or simulated), poor speed management in general, or possibly a skidding turn resulting from a desire to correct a late turn, and I have absolutely no idea how a plane of that size and/or complexity would respond to either of those situations.

Another possibility with cargo planes is something becoming unsecured and massively shifting the center of gravity, potentially beyond what the flight controls can compensate for.

An aircraft of that sophistication? If faceplace is telling me the truth that was a 1965 model and on its way to the boneyard (which is plausible given what I know about the PR tails). If that's true, then it was likely empty. Rumor mill says they may have lost an engine, but of course nobody will know anything for sure until the public release.

It has a stall warning system (up to and including a stick pusher?), GPWS, four engines and a flight crew of three. Other than a load shift (on a reported empty training flight to the boneyard), the only thing I can reasonably imagine is that an instructor pulled back two on the same side and it got away from them or maybe a prop runaway in reverse.

Well they should be on the same frequency when that close so open mic and "GOAROUNDGOAROUNDGOAROUNDGOAROUNDGOAROUND" could work. However one contributing factor to the Tenerife disaster was the Pan Am flight screaming on the radio for the Lufthansa flight to stop - this interfered with the tower screaming at the Lufthansa flight to stop so they only heard static.

Came here to post that. Estimated minimum vertical separation was 5 feet between the top of the taxiing vertical stab and the bottom of the Canadians. :catstare:

Edit: Slidebite, they did see them! Cockpit voice recorder has them querying ATC because they noticed lights on the percieved runway. ATC told them there was no traffic on 28R and they proceeded with the landing attempt despite reality not matching what they'd been told.

I know there were arguments, with merit I think, about the taxiway lights being easily mistaken for runway, but if they saw lights that could be distinguished as traffic and still proceeded... :catstare:++

Heres 102 pages on the subject: https://dms.ntsb.gov/public/61000-61499/61112/614631.pdf

quote:

The crew reported that the approach was flown, by the autopilot, until prior to the final waypoint
on the approach, which was labeled as F101D, at which point the captain disconnected the
autopilot and hand flew the remainder of the approach. The captain requested that the first officer
verify that their runway was clear. ATC voice recordings included the following10:
2355:45 ACA759 Just want to confirm this is air canada seven five nine we see some lights
on the runway there across the runway. Can you confirm we’re cleared to land?
2355:5211 ATCT air canada seven five nine confirmed cleared to land runway two eight
right. There’s no one on runway two eight right but you.
2355:59 United Airlines 1 Where’s this guy going
2356:02 United Airlines 1 He’s on the taxiway
2356:09 ATCT instructed ACA759 to go around
During post incident interviews, the first officer reported that prior to his query to the ATCT if the
runway was clear he was looking more inside the cockpit than out because, as the PM, he was
required to set the missed approach altitude and the anticipated heading for a missed approach.
These tasks required him to look inside at his approach chart to obtain that information. He further
stated that when the captain asked him to query the control tower, he looked outside, and it “didn’t
look right.” Although he was not certain what was incorrect, he was unable to process what he was
seeing. He subsequently commanded the go around to the captain by saying “go around go
around.” According to the captain, that was simultaneous to him beginning the go around. During
the initiation of the go around, the ATCT controller also issued go around instructions.
During the downwind leg for the second approach, the first officer asked the captain if they should
“tune in the ILS12” to which the captain agreed.

1.1 Previous Arrival – Crew Statement13
The flight preceding the incident flight landed on runway 28R about 4 minutes prior to the
incident. The flight crew of the preceding flight reported that the “construction lights were so
bright we could not determine the location of the inboard runway, 28L.” Visually acquiring the
runway, both crewmembers reported questioning if they were lined up for runway 28R; however,
after crosschecking with the LNAV14 they were able to determine they were lined-up for runway
28R.
They received additional confirmation about 300 feet above ground level (agl) when the
captain visually acquired the painted “28R” on the paved surface of the runway. The captain of
that flight further reported that the aircraft on taxiway C were stopped and had their taxi lights
off, which “helped to create this misconception that taxiway C was RWY 28R.”

One possibility there for some confusion at least.

Continuing to skim...
Captain:

quote:

On Friday, July 7, he fell asleep between 0200 and 0300 and awoke about 0745 by his children.
About 1120, crew scheduling called to notify him that he had been assigned a flight. He did not
take any naps that day and reported to the airport by 1940 for the flight. The incident flight departed
at 2125 EDT and this was the incident flight. Prior to the incident flight he considered himself
rested. He started feeling fatigued about midpoint on the incident flight, about the time they
encountered the area of thunderstorm activity.

FO seemed reasonably well rested, however lol at 9am being "sleeping in"

quote:

On Friday, July 7, the flight to Toronto arrived about 0030 and he went to bed about 0300. He
awoke about 0900. The rest of the day, he “took it easy.” His wife and kids were out so he was
able to sleep in. He had lunch around noon and took a 90-minute nap about 1300. He woke up
from the nap, spent time with his kids, had dinner and went back to work arriving at 1910 for a
1940 report time. He departed on the incident flight to SFO that evening. He stated that both he
and the captain began to feel tired about 0200-0300 EDT on Saturday, July 8.

ERM... Actually I have stellar scores on the surveys, and every year students tell me that my classes are the best ones they’ve ever taken.
I just wanted to brag that I apparently got the separation pretty drat close to correct in my mock-up image I posted back when the incident occurred :stonk:

Sagebrush posted:

No -- the lowest altitude would have been shortly after they pulled up. Takes a second to stop the descent before it begins to climb. When they hit 81 feet they were probably more like 10-15 degrees nose-up, depending on how terrified the pilots were.

It's a reasonable angle for the descent though iirc (I set it to 3 degrees)

However, if I do set it to 10 degrees nose-up, the image becomes even more terrifying, because the static port (from where the altitude is measured, though I dunno if 737s have radar altimeters or whatever) is located just below the cockpit. Putting that at 81 feet with 10 degree alpha...



Also, re. this:

Sagebrush posted:

If the FAA can use commercial flight simulators to reenact accidents, so can I! I made the same approach in X-Plane, which is known to have accurate and high-quality night lighting. I also photoshopped out 28L to simulate the appearance of the airport that night, more or less -- the runway was under construction, so its lights were off. There was apparently also a large illuminated X on the runway but I don't know what that looked like so I ignored it.

Anyway, yes the taxiway is parallel and everything, but it's still pretty unfathomable that they confused it with 28R:

I'm incredibly sorry for the loss of life in today's WC-130 crash, but I can't say I didn't expect it to happen eventually.

As someone who has personally laid hands and tools on a Puerto Rico ANG C-130, you could not pay me enough to get on one as PAX. Like literally I would pay whatever I needed to, and eat whatever administrative action/punishment I had to not to fly on one of their birds. About 10 years ago, I was in Europe doing an OEF/OIF support trip, and PRANG were the rotation relieving us. Their birds came in, and myself and another couple guys were tasked with putting their birds to bed for the evening, along with fixing anything fixable in the time left on our shift, while the rest of our unit threw the PRANG guys a welcome party. We opened the forms on one of their birds and there were discrepancies in the forms that were 18 months old. Of particular note was an autopilot discrepancy from many months previous that, by it's nature, would have rendered the autopilot system completely inoperable. We then verified the discrepancy and fixed the problem via a parts change. We came to realize later that this meant that they had manually flown the plane, hands on yoke, all the way from PR to central Europe. It's not a straight shot in a non-air refuel/non Benson tank equipped 130 either, I believe their route was PR->somewhere Eastern Seaboard (probably Norfolk)->St Johns->Shannon/Lakenheath/Mildenhall->our location. We later asked about this with some of the PR maintainers and got answers of "Yes, we didn't have autopilot". When we were later loading defensive flares, half the dispensers were installed upside down, which from experience, takes some real creative stretching of wire bundles. Those are only two of the things that rapidly come to mind, but they speak of a maintenance culture that is entirely foreign to me, and I wasn't even working on the propulsion/nitty-gritty airframe stuff at the time but I'm sure some of the crewchiefs that were there with me could tell similar stories.

I just turned off the lights on 28L, which is what the NOTAM said had been done. Didn't mess with the brightness of the others. Do pilots flying into a place like SFO regularly request that the brightness be changed? Is it possible that a previous flight had asked to dim the lighting on 28R, so there was less of a distinction?

In any case, one dim blue line vs a huge bright yellow line should be a pretty obvious distinction, and if they were confused because they were expecting to see two runways -- well, read the NOTAMs, that's what they're for.

I ask because there was a delta flight that landed on a taxiway at ATL in the middle of the night maybe 20 years ago and the NTSB report noted the lighting levels set were very odd looking from the air. ie they had the taxiway set to max and the runway set to minimum

There's not necessarily anything strange about a C-130 crew electing to continue with an inoperative autopilot. I saw it happen several times during long missions, and while it's a tremendous pain for the pilots, the autopilot system isn't technically required for flight. All it does is slash down the maximum flight duty period (normally 16 hrs / 18 hrs augmented, drops to 12 hrs / 16 hrs augmented without autopilot). I can't speak for their MXG choosing to deploy a bird with that issue, though.
