What's with all the low aircraft?

The past few days I have seen some unusual activity in the sky. There has been low flying straight-wing small jets and large prop planes flying low over the Center Harbor area. They have been flying two at a time.
One of the jets made a sharp u-turn, banking almost 90º.
They look like training flights.
Anybody have the scoop?

There was a recent mention of training exercises in the area on the news lately. They were going to practice threat scenarios that required intercepting small aircraft.

I was at the Kank yesterday. Several military jets buzzed around (one at a time). I think they were leaf peeping, just like the rest of us.

We were on the Kancamagus Highway yesterday and noticed two low fly byes by two military jets.
