Here we go. They were bigger. Probably F-35's.

Fighter jets train over Bethel

The planes are most often F-15 fighter jets flown by Air National Guard pilots from Westfield, Massachusetts. For a few weeks each year, F-35 jets fly over from South Burlington, Vermont on their way to the coast.

It could be training going on. Though that sounded bigger than an A-10. A couple of my neighbors came out to see what was going on. It was wicked loud.

Here's why there have been fighter jets over the Portland area this week

"They are A-10 Thunderbolts taking part in pilot training day for the #Maine Aviation Corporation."

Very loud, low-flying jet plane just shook up my neighborhood here in southern #Maine (not far from the Portland JetPort). My neighbor thinks it was a fighter plane, but we weren't able to see it because of the cloud cover. We often hear planes overhead, but never that loud. I wonder what's going on?
