I heard it in Boston and with initial reports saying it broke up over Cape Cod I was kind of surprised and just assumed a very big kaboom. There was a strong storm with 30knt wind from the North at the time. It makes a lot more sense that the shockwave was produced North of here at the NH border and travelled with the wind and the remnants falling East of here in the Bay.
PSA: meteors have nothing to do with explosions. The shockwave comes from meteor's movement alone, the parts never move apart with any speed comparable to their common forward motion.
A breakup will increase surface area and therefore kinetic energy to shockwave transfer efficiency, still not an explosion.
PSA: The word "explosion" has multiple definitions, plenty of which are actually quite reasonable to apply to meteors! It can refer to the sound alone, for example. The people reporting an explosion in Massachusetts were not incorrect!
It would however, be incorrect to claim that the meteor had noting to do with explosions.
No? There is no violent expansion or bursting, even if the sound is similar. It is as much an explosion as a supersonic jet passing by, and that is not much.
The term makes people think atmospheric heating causes an actual steam explosion and that's the source of shockwave, which can't be further from truth.
The Wikipedia article on "meteor air burst" has an explanation that basically matches yours, although they do use the word "explosion" to describe it. Which makes sense to me: whatever one chooses to call it, it's a nearly instantaneous spontaneous disassembly that is very bright, very hot, and very loud.
I didn't hear it in northern RI but all my friends heard it clearly. I feel left out

None of the definitions I found are concerned with only sound. One mentions sound as a result of an explosion.
PSA: expressing an opinion (incorrect or otherwise) is not actually a public service announcement

Probably just a UFO pickup gone bad.
