An American-born businessman wants to raise £1m to recreate the 9/11 attacks on the World Trade Centre by crashing a 747 into an abandoned building in Thailand.
Paul Salo, who now lives in Thailand, has started a fundraising page to raise funds for the reconstruction which he hopes will "once and for all" determine if conspiracy theories about the terror attack are right or wrong.
"If you doubt anything about 9/11, we want to blast this to smithereens, or we want to prove you completely right," Salo says in a video he uploaded to YouTube, and his September 11 Redux fundraising page.
Explaining the reconstruction which will see the plane flown on Autopilot, Salo said: "We're going to purchase a 747 or equivalent aircraft that's about to go out of service, we're going to fill it full of jet fuel, we're going to purchase a building that's about to be torn down in the countryside... and we're going to crash it at 500 miles per hour into that building.
"If there's just a smoking hole in the building and nothing happens, you pretty much know it was a hoax, right? Cos it's obvious, right?
"Sure, some people might be upset, but we deserve to find out what happened."
Salo said he has spoken to the Thai military about suitable locations for the "important project". If it is unable to proceed there, he said it may move to Africa or South America, and if the reconstruction fails for any reason, it will be attempted again.
Salo expects the reconstruction will prove that 9/11 was a terror attack - through "similar physics" - "but I'm no dummy, I want to make sure it's true".
Both the plane and building will be fitted with GoPro cameras, and the reconstruction will also be filmed from the ground. The plane's Black Box will also be examined after impact.
Salo is selling "front-row seats" to the reconstruction for £3,500. He is also calling on people to send him ideas and theories for the project to test.
He encouraged people tired of hearing conspiracy theories to donate so the debate could finally be concluded, and those who think it was a "major tragedy perpetrated on the world to start the war on terror... give us money too".
So far Salo has raised £72 from five backers. The fundraising campaign has two months left to run.
The terror attacks killed 2,996 people after two Boeing 767 planes hit the towers in New York on September 11, 2001.
Internet conspiracy theorists have long claimed that the World Trade Centre towers would not have crumpled so quickly - and that it was an "inside job".
Michael Moore's documentary Fahrenheit 9/11 added suspicion after detailing links between former president George Bush's family, the US Government and the Bin Laden family.
Cult film Loose Change, another 9/11 documentary, claimed that the attacks were planned by US government insiders.
