Twenty-five years later, one theory still won't stay buried. Here's what the evidence actually shows.

Summary: In this entry of The Tin Foil Diaries, we take on the most consequential conspiracy theory this show has ever covered: the claim that the U.S. government planned, assisted, or covered up the September 11th attacks. We start with Building 7 — the third tower most people forget ever fell — walk through the full "inside job" case as its most serious researchers actually argue it, and then hold every claim — thermite, war games, insider trading, the Pentagon — up against what independent engineers, chemists, and federal investigators actually found. Along the way, we reckon with the real human cost this theory has had on 9/11 families and survivors, and ask why a theory this painful for the people closest to the tragedy has still never lost its grip on the public imagination.

In this entry:

• Building 7: the third collapse on September 11th that almost nobody remembers, and why it became the theory's centerpiece
• The full "inside job" case: MIHOP and LIHOP, the war games, the put options, the missing $2.3 trillion, and the "New Pearl Harbor" memo
• What NIST's investigations actually found about why the Twin Towers and Building 7 collapsed
• The 2009 "active thermitic material" paper, and why independent chemists identified the chips as primer paint
• The Pentagon missile theory versus the FBI wreckage photos, DoD flight-path reconstruction, and eyewitness accounts
• The real, documented intelligence failures behind 9/11 — and why they aren't the same thing as a cover-up
• The toll this theory has taken on 9/11 families, survivors, and first responders
• Why a genuinely earned distrust of government keeps this theory alive twenty-five years later
