I saw this article last week and as i started reading i thought that they has mistakenly spotted the paper lanterns as i saw some of these last summer and wondered what they were (i even stopped to tell to two policemen who had stopped and got out of their patrol car looking skwards curiously) but when i read that people said they were mvoving twice as fast as an aeroplane i thought it couldn't be the same thing. How did people think they were moving at such high speed?
