What about the meta-metaphors of a literal "american airline" full of civilians minding its own business and following the rules and then literally t-boned by an american war machine. Also, they were leaving Dwight D. Eisenhower airport in Kansas. Eisenhower, the supreme commander of allied forces in WW2 who warned against the "military industrial complex". Wichita has so many air-related industries there that it was once known as the "Air capital of the world" and it's still its primary industry.
There's probably also something there about the fact that the plane was a Canadian one (Bombardier) whose name means "the guy releasing the bombs in a bomber". And also, the Bombardier company was started by a guy just trying to get people around (mass transit) in the winter time (via the first good snowmobiles B7, B12 - powered by american-made engines from Ford/Chrysler). And the helicopter was from a US company started by a Russian immigrant (Sikorsky) who immigrated to the US to escape the Russian Revolution after making bombers (that hold bombardiers) in WW1. And the helicopter crashed into a river, Potomac, named after the Algonquian word for a native american city and was itself named after a native american war chief (Black Hawk) that fought alongside the Canadians/British in the war of 1812 (where the white house and capitol were set on fire) to "push away white settlers". The helicopter left a fort (Fort Belvoir) named after a former slave plantation. The airfield it departed was named after a WW2 aviation engineer (Davison) and where Army One, the helicopter that carried Eisenhower, used to be based. In addition to the Black Hawks, the airfield is also home to 4 cessnas used in civilian air patrol - made in Wichita.
