Good point on how videos are not always shown in full to show them appearing or disappearing.
They look big to be lanterns, to me.
They probably are too big for lanterns... but I have seen some big ones.
I saw another news clip showing a different longer video that reported them as being flares. That video also doesn't show the floating lights disappear or zip out into space at a million miles an hour.
If I were filming this the camera wouldn't stop recording until the lights were gone. Come on.
The fact that they are literally described as Floating leads me to believe they are flares.
Cool video though.
We sent up some Chinese lanterns one night that my Dad brought back from Vietnam. They looked like total pieces of shit. I didn't think they would even work. I was dead wrong. Those damn things fly WAY up into the sky and lasted a long ass time. Once they get way up, it's hard to get a real size comparison... especially at night.
