First-Responder Rescue Truck From 9/11 Goes on Display at the National Air and Space Museum

Foam 331’s New Home

The tragic story of September 11, 2001 is inextricably tied to aviation, including the heroic efforts of the firefighters from Ronald Reagan Washington National Airport’s fire department. They were among the first to respond to the crash of American Airlines Flight 77, which was hijacked and flown into the Pentagon in Arlington, Virginia.

The National Air and Space Museum is recognizing that awful day and commemorating the National Airport firefighters with the acquisition of Foam 331, the first of two foam trucks to arrive that morning. Foam-carrying rescue trucks, often called “crash trucks,” are designed for the challenges of fighting fires resulting from aircraft accidents. These trucks use chemical foam to smother burning aviation fuel and are designed to drive over rough terrain near civil and military airfields. The Boeing 757 that was flown into the building on September 11 had nearly 20 tons of fuel on board. The Pentagon’s own foam truck had been heavily damaged, which made National Airport’s trucks the primary means of fighting the fire in those initial hours following the attack.

As members of the aircraft rescue and firefighting community, these first responders had critical experience in dealing with mass casualty events. The official Department of Defense history of the attack on the Pentagon offers a harrowing narrative of what confronted them: “In the first minutes, while some firefighters searched near the impact site, others set up the fire suppression equipment as rapidly as possible, with the immediate imperative to suppress the external fires caused by the spewed jet fuel that saturated whatever lay in its path. The explosion had generated a huge fireball that blasted outward, up and over the building…. Initial search and rescue missions were exceedingly dangerous. The firefighters did not know how far the fire had spread nor to what degree the building’s structural integrity was compromised.”

Foam 331’s journey to the Museum began in 1997, when it was purchased by the Metropolitan Washington Airports Authority. It was stationed at National Airport and then later at Washington Dulles International Airport before being sold in 2016 to a Canadian airport services operator, which planned to use it for parts. By 2019, the truck had been sold back to the manufacturer, Oshkosh Corporation, for scrap. Bill Stewart, a retired firefighter and training captain at National Airport, went looking for the truck as a way of honoring 9/11 first responders. After the truck was located, Stewart and the Museum worked with Oshkosh to have it prepped for display.

Visitors to the Museum can see Foam 331 at the Steven F. Udvar-Hazy Center in Chantilly, Virginia.

A New X Aircraft

NASA’s Sustainable Flight Demonstrator project hit a new milestone this past August when Boeing flew an MD-90 airliner to its facility in Palmdale, California, where the company will convert the MD-90 to an experimental aircraft, the X-66A. The project seeks to develop a new generation of more sustainable single-aisle passenger aircraft.

The transformation of the MD-90 will include replacing its wings with a new set that will be thinner and extra-long, stabilized by diagonal struts. The design concept, known as the transonic truss-braced wing configuration, will generate less drag and add more lift, potentially cutting fuel consumption by 30 percent.

The Not-So-Glamorous Lives of Pan Am’s Stewardesses

Few of the young women who became stewardesses at Pan American World Airways in the 1960s and ’70s envisioned the demands the job would require. The ostensibly glamorous career involved flying into active war zones in Vietnam, working in Cold War Moscow, and shepherding foreign dignitaries, U.S. service members, and refugees around the world.

In a lecture titled “The Pan Am Stewardess at War and Peace,” author Julia Cooke discusses the often-overlooked contributions of Pan Am stewardesses in addressing the geopolitical crises of the era, drawing from her book Come Fly the World: The Jet-Age Story of the Women of Pan Am.
