Mystery boom phenomenon.

Mystery booms have been heard across the globe for the past year, but mainly in the usa. They have trecently started up again but this time people are witnessing bright flashes before windows sucking in and out and even breaking. Sonic booms cannot break windows according to mythbusters so you cannot blame it on fighter jets. Besides it is illegal for pilots to break the sound barrier over residential areas and the military claim it’s nothing to do with them. But on one case where shop front widows were shattered from the boom, the airforce did come out and take photos and allegedly paid for damages but that is unconfirmed.
