While outside smoking a cigarette with friends I spotted what looked like a few meteors falling, without warning and in synchronization the lights slowed, swarmed like flies in the air.  Then swiftly and silently took off Southwest.
(White lights before slowing, transitioned blue like a far star before swarming and stayed blue when leaving.
