Here’s the setup: NORAD discovers a rapidly decelerating object headed for Earth; and predicts atmospheric entry in 15 minutes over the southern U.S., just enough time to call an alert but can take no other reasonable action.
15 minutes later, air traffic control at Hartsfield-Jackson Airport, (yes, I am from Atlanta ) having been alerted by NORAD notices a radar contact - the UFO is heading straight for them and is intending to land. ATC frantically waves off all traffic and the bogey comes in.
The ship (what it is is not important - flying saucer, Millennium Falcon, General Products hull, whatever) settles on the tarmac with thousands of airport passengers as witnesses; local news, network news, cable news - they’re all there in a heartbeat. No way can the feds cover this up; it’s all out in the open.
A doorway appears in the ship. A figure steps out.
What happens next?
My only assumption - this is a First Contact, not an invasion. How do you *reasonably * think humanity would react?
