4 rectangle solid red lights in a right banking turn. then each blinked once and went out. 4-3-2-1Traveling from north east in a banking turn to the south west. looked to be around 2-3 thousand feet high. Rectangles were outlined in black with very bright red light inside.Speed seemed to slow for an object that long in length to be able to stay airborne. No sound at all. There were four rectangle objects in perfect in-line formation. each the same size, banking right in turn. I put my fist out and there length exceeded my fist.the angle of all four was about 130 degrees. All four were solid red in color. Then top #4 blinked once then went out, #3 then blinked once and then went out.#2 and #1 followed in same order. Myself and neighbor both watched them for a full 30 seconds before all went out.
