I was sitting on the porch by the beach in swampscott, massachusetts. my friend and i noticed some red lights on in an array like the tail of a kite. they were diamond shaped and i thought at first they were fireworks but they were bigger. they rose from the ground into the air and hovered until they went out of sight. the whole event lasted anywhere from 3 to 7 minutes. they hovered like helicopters or drones. i don't think they were drones because they were so visible from where we sat. and we were maybe 10 to 25 miles from where we saw them.
