Experts Explain Truth Behind 9/11 Conspiracy That Airplane Fuel Cannot Melt Steel
A popular conspiracy theory that emerged in the wake of the September 11 terrorist attack on the World Trade Center is that explosives were used to demolish the building.
This theory suggests that since the jet fuel does not burn hot enough to melt the steel beams, the building must have been destroyed by other means, such as planted bombs.
But, in 2005, experts released a report explaining the findings of the building and fire safety investigation of the World Trade Center disaster, which debunks these claims.
The report states that if “the specified minimum thickness of insulation was sufficient to retard the heating of farms; however, the amount of insulation dislodged by the impact of the aircraft was sufficient to heat the structural steel to critical levels ”.
This means that since the insulation that protected the steel was struck, the metal was able to reach temperatures that made it unstable.
The report goes on to explain: “Bare steel framing members, when exposed to a large and sustained fire, can heat up quickly to the point that their ability to carry their load is compromised.
“Thus, insulation is generally used to encapsulate steel and thereby retard the heating of the steel.”

After the plane struck the towers and the fire started to spread, gases were released into the buildings.
As a result, the report states that: “The perimeter columns, floors and center columns were submerged in these hot gases and began to weaken.
“At temperatures of around 300 ° C, steel loses about 20% of its yield strength (Figure 2-9).
“Under modest loads, steel is elastic, which means it can compress or shorten, but will recover when the loads are removed.
“As the load increases, the steel becomes plastic and the fat is irrecoverable.
“At temperatures above 500 ° C, the steel weakens further, the loss of strength and rigidity becomes significant, and the ability of the column to support its share of the building loads decreases. “
In parts of the Twin Towers, temperatures reached 600 ° C and even a scorching 1000 ° C.
“As a steel column is heated, its ability to support gravity loads and resist lateral loads decreases,” say the experts.
While the fire may not have completely melted the steel, it most certainly heated the beams to a point where they would warp and sag, causing the building to collapse.
