Four Chinooks...

...just came hammering over my house.

If I hear aircraft over the house, I usually go look, but this time I was busy and guessed that it was probably just the ER helicopter. But the noise got louder...and louder...and louder...and by the time I got outside, it was shaking the whole house.

Anyway: four Chinooks. Dunno what model--I'm not that knowledgeable about them.

No idea what they're up to.

As you can probably infer from the above: this isn't a common occurrence here--never seen such a thing before, actually.
