There have been multiple news stories over the last few years about mysterious booms sometimes accompanied with flashes of light in the middle of the night all over the country (look it up, mysterious booms.) I wonder if this balloon problem happens more often than we think. Or if it did in fact have an explosive on board to self destruct and did self destruct upon mission end? This would be a plausible explanation for the booms and flashes of light over the last few years IMO. Just something interesting I remembered reading and following.
