Which is why these installs usually involve all sorts of external waterproofing, concrete encasement, galvanic/cathodic protections & sacrificial anodes, drainage systems, and interior climate control. They don't just bury the expensive fuselage and call it a day.
No, but the aluminum in the fuselage requires all these mitigations and it’s a well known problem. Without them, galvanic corrosion weakens both the aluminum and the concrete.
I wouldn't call it common. It is a time consuming hobby at best. However I expect a lot of people spend time daydreaming about their future bunker that they never build and I would expect a plane to come up with something to bury quite often. Many of those are enough of engineers to figure out details like this.
Even this is the first time someone actually does it.
The video says the guys wants to put the hull under a 3 inch fiber-reinforced concrete vault, which would be supported by the plane. The guy's word: "I'm hoping the plane can take that sort of weight". Then another thicker layer of concrete this time reinforced with mesh.
I for sure hope the guy hires good engineers to do the actual calculation and the whole "I don't know what I'm doing" is just for the show.
You can see the rebar in the photos so that checks out, and I would think without it a plane wouldn't be designed to withstand force from above like you would need to be able to bury it safely. If I buried something like this in my yard it would need to be able to withstand a utility truck driving over it at least once in a blue moon.
Concrete is not very water proof on its own. It's also quite hard to prevent cracks from forming, even with reinforcement.
There is a lot you could do, like neoprene barriers on the skin of the fuselage, sacrificial anodes, spray sealant on the poured concrete. But at that point, you might as well not even have the fuselage and just build a regular, ol' concrete bunker.
It doesn't look dense urban, things are very often more relaxed in semi rural areas and low density zones; further he has existing underground structures that I would guess have already been approved.
If I had to, I'd bet he's had a conversation with a local planner and had a nod and a wink already.
It also helps that he has a fairly popular YouTube channel. I expect the locals are aware of that and so they're even less likely to do something because they know that there will be a public outcry.

Tbh I'm not entirely sure I'd trust a partial plane body to have the mechanical strength for the job. In flight the pressure is pushing out not in, and I assume that's what the thing is designed for.
Though the thing is only barely buried so I suppose it doesn't actually have much external pressure to deal with.
He is pouring concrete re-enforcement around it. Biggest issue is during the pour which he seems to have planned in stages to not put too much pressure on it.
Few minutes in and he is mixing concrete: Too much water in this concrete mix. Wrong kind of sand as well... Luckily he seems to have had a professional mix the concrete for the walls, etc.
Ideally, tank your hole with a membrane and pump. Only a noob garden-plane-in-hole owner would crane it in without one! Bit late now.
On the up-side, it looks like it's going into a concrete clad hole so may have a cavity not be buried in soil. It won't be permeable like basement walls that suck water out of the ground. I guess it's aluminium/titanium so won't be red dust by spring but can still corrode in some fashion depending on ph/oxygen. Could there be steel in things like fasteners?
Oh, and it's a tube... no idea how they've sealed the ends.
> He aims to apply for retrospective planning permission on the project, which he hopes to have finished by February.
Isn't that a bit risky? Is the idea that his YouTube popularity will mean the council won't say no?
Also, Bmibaby, what a blast from the past
Could go the other way as well, the publicity causing them to do things the "right way".
A 737 fuselage is made of aluminum, which will corrode with rain, salts, and sulfates present in most soils.
Which is why these installs usually involve all sorts of external waterproofing, concrete encasement, galvanic/cathodic protections & sacrificial anodes, drainage systems, and interior climate control. They don't just bury the expensive fuselage and call it a day.
Serious question - is burying a plane fuselage to create an underground bunker a common enough thing that there is a usual way of doing it?
No, but the aluminum in the fuselage requires all these mitigations and it’s a well known problem. Without them, galvanic corrosion weakens both the aluminum and the concrete.

No, it is stupid idea.

Wanted to check how long the process would take buried naked and cursory search is maybe 5 to 15 years. Sooner with wet weather.
It's sitting on a concrete base and will have concrete pours around it.

Usually you see these done with large pipes or school busses, but the pipes are better. https://www.youtube.com/watch?v=z7bM8-hcgsI
Which is only a problem if it’s in contact with the soil.

It's often easier to get retroactive planning permission, and I suspect an underground bunker isn't as likely to get denied as something more visible.

Probably so in foresight that burrowing an airplane would be quite a long dispute to start with.
Heh. My partner has to put up with my ideas of digging up the driveway into a trench laying down containers and then putting a new driveway on top.
I take it they aren't a huge Colin Furze fan, unlike yourself?
He should talk to Colin furze
Colin furze was there to help lower the plane
Pretty sure they've done stuff together on YouTube.
Yep. Furze also recommended the channel on his most recent video.
I don't understand the idea, the hole seems vastly too shallow to protect effectively from for example, bombing.
They have a YouTube channel, so I'm sure it is just as much for views as anything else.
It's... the very first line of the article

I was expecting something more like this from the title:
https://www.reddit.com/r/abandoned/comments/1x4yw6y/inside_t...
"The first friend he discussed the idea with told him it was "silly", so he went to his seven-year-old son for guidance."
This is the best feedback he could get to be sure it will run well you YT.
The planning permission situation could end up being more interesting than the actual construction..
How long until someone in Reddit points out at asphyxiation hazard, fire hazard, and the fact that the plane used to transport dangerous chemicals?

I think the planning permission issue is probably even more pressing
The video version:

There's also a bunch of other videos of other stages of the project up to this point.
Few minutes in and he is mixing concrete: Too much water in this concrete mix. Wrong kind of sand as well... Luckily he seems to have had a professional mix the concrete for the walls, etc.
How do you protect against damp in this set-up?

He has an old well on the property that's dry most of the year so we have reasonable assurance that the groundwater level is not hot that high.
With a large sheet of plastic I suppose. Which apparently they forgot to add.
