Man burying a Boeing 737 to build an underground bunker shows the inside of the plane

This YouTuber bought a retired Boeing 737 passenger jet and decided to bury it underground.

Instead of scrapping the aircraft or putting it on display, he’s decided to turn this Boeing 737 into part of a private bunker.

The plan is to connect the aircraft to an existing network of tunnels below his property.

And it’s one of the largest underground builds he’s attempted so far.

What the inside of the buried Boeing 737 actually looks like

Before the plane disappeared into the ground, Tornado Dave showed us what’s left inside it.

The cabin has been stripped down to the airframe. 

There are no seats, no panels, and no trim – just the structure that holds the aircraft together. 

You can see the metal ribs, the cable runs, ventilation ducts, pulleys, and exposed mechanical parts running the length of the fuselage.

Without the interior installed, the aircraft looks far lighter than it does in service. 

Dave even says some sections resemble a caravan more than a jetliner, which is an odd thing to hear about something that once carried hundreds of passengers at cruising altitude.

The tail section shows this most clearly. 

Panels move when you push them, vents open and close through mechanical linkages, and internal parts shift as the structure flexes. 

Thick bundles of cables, heavy fittings, and labeled Boeing components are packed into tight spaces, all did jobs passengers never saw.

In the video, Dave stopped to look at parts he didn’t know existed, pointing out mechanisms he planned to reuse elsewhere. 

He called some of it a work of art, and from an engineering point of view, it’s hard to argue.

And the price is the craziest part. 

Dave said he paid about $5,000 (£4,000) for the aircraft section, which includes roughly seven tons of aluminum and titanium.

There are issues, though. 

He spotted gaps where you can see straight through to the ground and admits the structure will need reinforcing before it’s buried.

Why he’s burying a plane instead of using shipping containers

Dave has buried shipping containers before, and he says they’ve reached their limit.

Once you insulate them and add structure, they get cramped fast. 

A plane fuselage is longer, curved, and built to carry people and systems for long periods, which makes it a better starting point underground.

The plan is to strengthen the inside of the Boeing 737 with steel mesh, add insulation, then lower the plane into a trench and encase it in concrete. 

From there, it will connect to an existing tunnel network already under the property.

There’s even talk of adding a bar area off the plane later on.

It’s a strange end for a passenger jet, but as bunker builds go, this one is hard to top.
