Fact check: False claim that barrels pictured on planes contain ‘chemtrails’

The claim: Photos show ‘barrels of chemtrails’ on planes

Some conspiracy theorists believe the white trails left by airplanes in the sky are “chemtrails,” toxic chemicals supposedly added to the atmosphere by governments or other nefarious actors.

There’s no evidence of this, as scientists and airplane pilots have repeatedly maintained, yet claims to the contrary continue to circulate on social media.

A Nov. 29 Facebook post (direct link, archive link) features three images that the post claims show “barrel’s (sic) of chemtrails” inside various aircraft. The post was shared more than 500 times in one week.

But the claim is false.

The bottom photos show different kinds of ballast barrels filled with water. Ballast barrels are commonly used by aircraft manufacturers to control the center of gravity and simulate the weight of passengers on test flights for new planes.

The top photo shows fuel tanks used for long-distance flights.

Containers pictured in post hold fuel and water, not dangerous chemicals

The containers featured in the post’s top image are marked with the Hawaiian Airlines logo. Alex Da Silva, a representative for Hawaiian Airlines, confirmed the containers fuel tanks used for long-distance flights.

“These are fuel tanks used to boost the range of our short-haul 717s when we need to fly them longer distances for heavy maintenance,” Da Silva said in an email to USA TODAY.

The bottom right photo in the post includes a caption that indicates it was taken on an Airbus airplane.

MaryAnne Greczyn, a spokesperson for Airbus, confirmed the image shows barrels filled with water on an Airbus test plane. She said using water tanks and ballasts to test new airplanes has been an industry standard for decades.

“Different weight and center of gravity test campaigns are essential to qualify and certify a new aircraft for its passenger or cargo service,” Greczyn said in an email to USA TODAY. “Water tanks are a very simple and flexible way to simulate more or less weight during the test campaigns.”

The ballast barrels in the bottom left photo appear similar in size and shape to the ballast barrels used by Boeing to test new models of aircraft.

Boeing Chief Pilot Van Chaney described the barrels’ use in a video tour of the Boeing 747-9 aircraft.

“The first thing you’ll notice are these large, black barrels,” Chaney says in the video. “We have two sets of these, at the front of the airplane and at the back of the airplane. Water is transferred from the back to the front, or the front to the back, to very tightly control the center of gravity of the aircraft.”

Chaney also points out pallets on the plane used to hold lead ballast barrels, like the barrels pictured on the Airbus aircraft.

USA TODAY and other news outlets have debunked a multitude of false claims regarding the chemtrails theory.

Our rating: False

Based on our research, we rate FALSE the claim that photos show “barrels of chemtrails” on planes. The photos show ballast barrels filled with water for aircraft testing and fuel tanks used for long-distance flights. There’s no evidence anyone is adding “chemtrails” and toxic chemicals to the atmosphere by plane.
