Beneath a quiet street in Hilton, Derbyshire, sits a massive subterranean engineering marvel. A 44-year-old engineer named Dave Billings—known to his 277,000 YouTube subscribers as “Tornado Dave”—has spent 11 years digging beneath his home. Now, his latest expansion involves burying a massive commercial airliner in his back garden.

The dave billings airplane bunker is a subterranean fallout shelter in Derbyshire, England, built by YouTube creator “Tornado Dave.” Valued at over £54,000, the 140-foot underground network connects a hand-dug tunnel to a retired Bmibaby Boeing 737-500 fuselage, featuring water filtration, blast doors, and emergency survival supplies.

Key Takeaways (TL;DR)

• The project evolved from a £50,000 tunnel inspired by The Great Escape into a heavy-duty survival shelter.
• Billings recently bought a retired Bmibaby Boeing 737-500 fuselage for £4,000 on Facebook Marketplace.
• The 7-ton aircraft will sit 14 feet underground and connect directly to his existing tunnel network.
• Upgrades include off-grid well water filtration, fresh air scrubbers, and reinforced steel blast doors.

The Evolution of the Tornado Dave Bunker

From ‘The Great Escape’ to a 140ft Subterranean Network

The project started over a decade ago when Billings discovered an old World War II water well on his property. The land formerly housed a US Army military camp complete with Nissen huts. He used this disused well as the primary access point for his first underground room.

Driven by a childhood fascination with the film The Great Escape, he spent months digging a 35-foot tunnel by hand. Using just a battery-powered drill, he advanced at a rate of one foot per day. Today, that tunnel connects to a 140ft multi-room facility featuring a gym, a sink, and a vertical beer lift disguised as a keg.

Acquiring the Bmibaby Boeing 737 Fuselage

Earlier this year, Billings spotted a redundant 1993 aircraft shell on Facebook Marketplace. He bought the retired Boeing 737 fuselage for just £4,000. He immediately realized it offered the perfect width and length to expand his underground man cave.

He plans to preserve the rear vacuum toilet and the authentic galley shelving. He will even install working ovens in the original galley area. However, he is stripping the plastic interior insulation away to expose the rugged, industrial aluminium framework underneath.

Visitors will eventually enter through an original plane door and walk down an airport-style corridor. At the far end, an old phone box will hide a vertical lift leading back to the surface.

The £54,000 Build: Cost Breakdown & Specifications

Building the dave billings airplane bunker requires serious financial investment. He estimates the initial multi-room build cost around £50,000. Adding the aircraft and survival gear pushes the total value significantly higher.

Structural Engineering: How Do You Bury a Commercial Plane?

Structural Engineering Breakdown: Managing Soil Pressure A commercial airliner fuselage is built to handle massive internal pressurization at 35,000 feet. It is not designed to withstand the external, crushing weight of wet Derbyshire soil. If you simply buried a 7-ton aluminium tube in the ground, the earth would crush it completely. To prevent this, Billings must dig a massive trench, surround the fuselage in heavy steel mesh reinforcement, and encase the entire structure in poured concrete.

Shipping containers often buckle under the weight of wet soil because their flat roofs lack structural integrity. The curved shape of an airliner provides better natural resistance to external force, but the added concrete shell is absolutely mandatory for safety.

Upgrading for WW3: Survival & Off-Grid Prep

With global tensions rising, the dave billings airplane bunker is transforming from a fun novelty space into a serious survival facility. He is investing an additional £10,000 into heavy-duty disaster preparation.

He plans to install an off-grid water filtration unit to safely drink from the original WW2 well. He is also stocking long-term dry food supplies and adding mechanical air scrubbers. Finally, heavy steel blast doors will replace standard entryways to protect the space from severe external explosions.

While he admits the shelter is not entirely “nuclear-proof,” it offers heavy protection against conventional fallout and emergencies. He views it as a modern equivalent to the Anderson shelters used by British families during the Blitz.

Wrapping Up the Build

The dave billings airplane bunker represents one of the most ambitious DIY engineering projects in the UK. By combining a 140ft tunnel, a WW2 well, and a £4,000 passenger jet, Tornado Dave has built an incredible off-grid sanctuary.

The project perfectly highlights a growing UK trend of extreme DIY architecture and emergency preparedness. Whether you want to build a simple garden room or dig your own survival shelter, Billings proves that with enough battery-powered drills and determination, you can build almost anything.

FAQs

Where is Dave Billings’ underground bunker located?

It sits beneath his family property in the quiet village of Hilton, Derbyshire.

How much did the Tornado Dave bunker cost to build?

The initial 140ft tunnel network cost around £50,000, with the recent Boeing 737 addition and planned survival upgrades adding another £14,000 to the total.

What kind of plane did Dave Billings buy for his bunker?

He bought the fuselage of a retired 1993 Bmibaby Boeing 737-500 passenger jet.

How deep is the Tornado Dave tunnel network?

The new aircraft section will sit 14 feet underground, connecting to a hand-dug tunnel roughly 35 feet long.

Is the Dave Billings bunker nuclear-proof?

No. He explicitly states it is not a fully nuclear-proof bunker, but it acts as a highly effective fallout and survival shelter.

How did Tornado Dave dig his underground tunnel?

He dug the initial 35-foot tunnel by hand at a rate of one foot per day using a battery-powered drill.

Can a buried airplane withstand the weight of the dirt?

Not on its own. The aluminium fuselage must be heavily reinforced with steel mesh and encased in concrete to prevent the soil from crushing it.
