Someone has decoded the mysterious noises from the Boeing Starliner spacecraft. It’s not what anyone thought.

If you’ve been keeping up on what’s happening on the International Space Station, you’ll know that Boeing really pooched it with its Starliner spacecraft, turning a one-week astronaut visit to one that won’t end until sometime in February 2025.

The Starliner has all kinds of malfunctions and equipment failures. And now, there’s a mysterious sound coming from the vehicle. At first, no one at Boeing or NASA had any idea what this sound is–except this guy. (Note: The mystery has been solved.)

Take a listen.
