I let off my own lanterns last year in asia where its common around new year (they are banned in western counties due to flight risk thus why we freak out when we see them!). They are very large, make no sound and hover. Its quite obvious to me when i see these now, if you disagree with my thoughts here then please respond. I just ask that people use their brains and think hard when you see a light in the sky - could there be another explanation for it?
Banning of Chinese Lanterns - a good thing for Ufology & farmers.
Overall a ban on sky lanterns is a good thing for ufology, less fakes leaves more room for genuine sightings.
