Those are MD-10s, which is an important distinction here because it’d be McDonnell-Douglas letterhead on the parts, not Douglas.

The MD-10 is a DC-10 with a MD-11 cockpit so they can be the same type.


edit: I guess that’s wrong:.. Wikipedia claims it there are 12 MD-10s flying and 0 DC-10s so idk what’s up with the Douglas thing. It’s 11 FedEx and 1 flown by Bolivia.

#2 isn't ALWAYS bad...

The MD-10s are an STC on DC-10-10s and DC-10-30s, while MD-11s are on a different Type Certificate. Anything regarding MD-10s that isn’t specific to the STC will be on the DC-10 TC, and thus parts will reference the DC-10 IPC/MM. (Which has Douglas headers.)

I saw that in the original thread, no idea if it's true but it would rule so hard

Yeah I don't think it's an inherently plane problem, just something we created. I certainly had to go through security for trains in Chian and Uzbekistan for example.

Meanwhile I can get on an EU flight within 15 minutes from entering my airport, including security checks.

The only real thing trains have over planes as far as inherent need for security is that its harder to kill people not on the train during a hijacking. Planes didn't even used to have metal detectors until a black guy got beat up in the 70s by some dirty cops so he and two friends hijacked Southern Airways Flight 49* and threatened to crash it into Oak Ridge if they didn't get to talk to Nixon about it. I assume trains will get more security if someone ever finds a way to cause a huge chemical spill or something.

*I'd link wikipedia, but the page kinda sucks. You'd probably be better getting details from anywhere else.

DO YOU HEAR THAT? THAT'S THE SOUND OF ME PATTING MYSELF ON THE BACK.


Honestly, security isn't even the main concern and that's something that's pretty solvable by streamlining the flow.

For one, the whole "SHOE BOMB" and liquid concern likely isn't that big of a concern on a train ever since you don't have to worry as much about a hull breach or a structural breakup 5 miles above the surface of the planet. As long as someone can't get something onboard large enough to derail the train, a localized small explosion or fire isn't going to be a huge safety concern for the whole train like it is on an airplane. A train can just...stop. It doesn't have to maintain structural integrity and life support for dozens of minutes and then perform a structurally stressful procedure to get on the ground nor is it going to store fuel throughout the structure that can be set on fire or does it need specific weather conditions to stop. You also can't exactly hijack a train to get you to a different destination.

So, if you limit the security screening down to a metal detector/body scan, bag xray, and some explosive sniffing, things would move through pretty quickly. No taking off shoes and taking crap out of bags and whatnot. Just make sure someone doesn't have a gun or a machete and move people through.

Beyond that, the main holdups in airports are delays and the taxi/gate wrangling to keep delays from compounding along with weather delays. The trains should largely run on time as long as there aren't maintenance concerns which would move people though the station, at a predictable pace so you don't need plan so far ahead that you are at your gate an hour before takeoff.

Yeah, I took the train a few times in Spain and it was “throw your bag through the scanner and then head to your gate”. I don’t even remember a metal detector. It’s not like they haven’t had an experience with terrorism on trains either.

i think passenger capacity is closer to a MD-90, it's listed as 114-180 on wikpedia which we all know is accurate. they are extremely performant from a power-to-weight perspective even compared to say, the 727, but that means they're very thirsty, noisy and maintenance pigs. but compared to "not having planes" they are a pretty good answer. they've been successively grounded by different organizations due to age but i don't see the Russian Federation having a lot of other decent options.

There's an episode of Mayday or one of those airline disaster shows that covers this with the pilots themselves describing what happened over re-enactments. Jesus loving Christ, that was too ridiculous for a movie. Dude getting his skull fractured with a hammer, there's a spear-gun involved somewhere in there, one pilot unable to do much in the cockpit because he had a brain injury, another pulling some flying out of an Airport movie to try to throw the attacker off his feet, it was bonkers.

Robinsons have a notoriously finicky rotor system. They're horribly prone to something called "mast bumping" (and the mast on the Robinsons are super prominent) which is where the rotor assembly can impact the mast that it sits on. Occasionally the entire rotor system will come off, other times it can slice off the tail or go into the cabin. My guess is the rotor tilted too much, cut off the tail (which you can see early on in the video flitting around independently of the helo), and then the rotor, which was still turning as the pilot probably *tried* to get level and autorotate, hit the mast again and just broke.

They are the deadliest helicopters data-wise in the part of the world where records are kept and I will never fly in one.

That article is pretty bad and written by someone who's been spoon-fed what to write.

I think it's unlikely that the main bladed hit the tail boom or that he mast-bumped it. The main blades and rotor assembly in general looks intact (until it *does* hit the remaining tail boom).
The prominence of the mast on the Robbies have nothing to do with being more prone to mast bumping.
Mast bumping can happen in any semi-rigid (underslung rotor head). When the disk gets unloaded during a low G maneuver, the helicopter can start to roll left as the rotor can no longer counter the force from the tail rotor (as it's mounted above the central axis of the heli). If the pilot then counters, the blade can, again, due to the lack of load, flap fully right and the bottom the of the rotor assembly can start 'bumping' the mast, potentially causing the mast to fail and the rotor to separate.

I think it has far more to do with the typical operator of the R44's being low hour pilots.
The R22 uses identical design, but is primarily used for flight instruction, so a responsible adult will be on board the majority of the time.

Yes, and that pilot performed an excellent autorotating landing, but the cause was ultimately pilot error because he forgot to turn the magnetos on or something like that

I feel like most instructors are always low hour guys. Very few people instruct for a living. Those that do are typically to get through a transitory phase of their aviation career.

Being a low hour guy doesn’t mean you aren’t safe. You may not have the experience of a higher hour pilot but that often induces caution and conservative judgement.
