5 small triangle or V shaped aircrafts making a short passing over just barely above the treetops

I was laying down in a hammock with my boyfriend when all of a sudden we start to see this light green haze of a light. At first we thought they were birds due to spring rolling around, but upon further looking these were completely silent and moving perfectly in a straight line. As well as seeming to be overlapping. The ships themselves weren't very big, and the only way you could see this was by the light coming off of them. They were around 3 FT wide and 1 1/2 FT long.
