General Dynamics took the B-57 Canberra bomber and stretched its wing to over 122 feet, creating an aircraft that cruises above 60,000 feet. Only 21 were converted, and NASA flies the survivors from Houston on science missions — chasing total eclipses, sampling the stratosphere, and filming rocket launches from above the weather.

Fun fact

NASA's WB-57Fs filmed the 2024 total solar eclipse and SpaceX Starship launches from above 60,000 feet — where the sky overhead starts to go dark.

How to spot one

You will rarely see one — it works above 60,000 feet. On climb-out from Houston: an impossibly long, straight wing, two fat engine pods, and a dark sensor nose.

Sounds like
Two TF33 turbofans — a muted, steady whine built for the thin air twice as high as the airliners

One might be overhead right now.

Bogey turns the The Stratosphere Lab from a dot in the sky into a card in your logbook.
