Multiple (8-12) white glowing orbs passed over the clinton hill neighborhood of brooklyn around 9pm on 11/15/19. the group of orbs, that were in a angular formation, passed over an apartment building cruising at about 20-30,000 feet. i observed the group for about a minute and a half before the formation entered a group of clouds and vanished. they moved seemingly completely silent across the sky. i should also mention that they were heading s.E. in the direction of local commercial aircraft. i only had my cellphone with me and thus was not able to photograph or record in the time allotted during the event.
