No, Alabama, we were not under attack last night. The loud boom some Alabamians heard late Tuesday night was the result of a space craft roaring back into the atmosphere before splashing down in the Gulf of Mexico.

Many residents, particularly in the lower half of the state, reported hearing the sound.

Some called 911 in panic.

The SpaceX capsule and four crew members eventually splashed down into the Gulf close to Panama City, Florida.
