How Does The Boeing Dreamlifter’s Swing Tail Door Work?

Beoing could of use the space shuttle loaded bay technology instead of the swingtail.and maintains a rear apu system. Or add a apu pod under a wing

I worked on the software for and commissioned a couple of the Tail Support Stands, the highly modified Hyster that opens tail. I was also there for the first opening taking measurements to make sure nothing got damaged. They are really impressive planes and it was a really cool project to work on.

Nice video! I have never seen one in person.

I was the Business Manager on the program during design, build, modify, flight test phases and its first operational flight. Not seeing it flying into Everett has been a disappointment.

If it does not have an APU, how it would do an in-flight restart if the engines were happening to be flamed out? [Considering windmill method does not work].

My brother-in-law works for Atlas as a loadmaster in Wichita, Ks. Works out of McConnell AFB. They are a sweet aircraft! I remember when one landed at a GA airport not designed for anything that big a few years back on accident

Never seen a dreamlifter (specially here in the philippines) but i think boeing made a good transport aircraft

Beluga XL over the dreamlifter for sure

Why even mention the Airbus Beluga as an option; I can't imagine Boeing would swallow its pride and choose a competitor aircraft to transport its parts....lol

The Beluga XL looks cleaner and sleeker than the Dreamlifter in my perspective, so Airbus is better

Love the Airbus Beluga/XL than the Dreamlifter.

👍🏻 Boeing saved its reputation in high capacity class as it bigger and carries more weight than beluga XL, plus it looks away much cooler than beluga. Boeing nailed it. Hopefully they will build more of this in future as demand for outsourcing grows.

If the DreamLifter was based on the 747-400, how come there were no winglets? Is it based on the -400D, or did they remove them for some other reason?

better than Beluga I’ve seen ot at Boeing Field

N747BC, came to SLC last July. Dreamliner wings in main cargo area (stayed on) and 500,000 masks in the bellies, lol.

Yes

When I was at the Everett factory one landed as soon as o got back from my tour, as well an antonov 124 was parked at the museum

Only things have been lifted are nightmares.

747 wearing a coat

They frequently visit MIA. Seen them parked at the Old Eastern Airlines section of MIA.

This plane is different from a 747, so why couldn't placing the APU in the nose work?

I have done the ramp work for it, in fact I have pushed it. Not going to lie, it is quite annoying having to use an air start on it.

These Dreamlifters were modified in Taiwan by Evergreen Aviation Technologies Corp.

Would we see a -8 version in the near future?

I’m sorry but it is really ugly! The Beluga looks beautiful compared to it! 😂

Queen got pregnant

Simple flying do a video why;
(1) 787 10 has 2 instead of 3 wheels in main gear
(2) a330 freighter has a hump like on its nose gear housing

You didn’t mention one important engineering challenge in this project: the Boeing 747‘s control surfaces are operated by steel cables routed from the cockpit all the way to the tail. When swinging a part of the fuselage open and closing it again, you have to ensure proper functioning and pre-tension of these cables, so the controls work properly and you have no play or risk control surface flutter.
The Super Guppy that Airbus used before the Belugas had the same issue when swinging open it’s nose. By lowering the cockpit, Airbus managed to keep airframe and control systems untouched during daily operations, opening and closing just a ‘regular’ door without interfering with primary structure or control systems, and thereby solving a major disadvantage of the Super Guppy.
It would be interesting to know why Boeing’s engineers chose not to follow the same path of improvement.

Got a chance to see it at Nagoya in Japan

Just wondering and I'm sure Boeing would have looked into building a civilian C-17 instead of the building the Dreamlifter. Is the C-17 smaller?

Im from seattle so i used to see these flying over a lot when dream liner production was still ehre

No and no.

Great video. ☺️

Unlike airbus the Dreamlifter actually used to be a passenger plane. Two were Malaysia Airlines, one Air China, and one China Airlines. Strange…

I think the dreamlifter looks really ugly but the beluga looks great

It’s just an oversized Canadair CL-44 😂

4. N780BA

What happends when it opens in-flight....🧐🧐

Seeing belugas (now XL ones) nearly every day I'm always surprised when I see the tail of a dreamlitfter swinging back

The swing tail of a bird which looks liie a fish.

Ironic

Can you make video about The Beluga XL now pls

I got to witness the Dreamlifter at Boeing Field in Everette, Washington back in 2016. I got to see two of them take off! They are absolutely IMMENSE!

I just feel like Airbus did waaay better with the Beluga, no tail-coming-off possiblity and an APU, it's just plane better

I always wanted to know how this ugly guppy boeing plane opens its huge Tail

Very nice.

beluga xl i will prefer

Yes! I saw several of them in Everett! They are really impressive!!!😍😍😍

Dreamlifter is much bigger than Beluga. I've got the privilege to see it quite often arriving and departing from my hometown airport Grottaglie (ITALY), where there is the Leonardo plant for the 787 fuselage production.

One in Anchorage, Alaska today.

OK Tom, since the tail is hinged, they must have removed the rear pressure bulkhead, meaning the fuselage is unpressurized, don't you think ? only the cockpit and upper deck pressurized. I think the An-225 is the same. good vid, thanks !
