They answer all the questions themselves',glowing red lights ,burn themselves out ,floating"

Could it be they were burning lights floating?? pure genius on behalf of these reporters

Not only are they a fire hazard they are a danger to livestock. Many farm animals in the UK have died as a result of eating the wire that holds the lanterns in shape.

A chinese lantern fell from the sky in the UK and caused horrific burns to a young child a while back.
They do now sell biodegradable versions which are claimed to be safe for livestock,but the fire hazard is still present.
The danger increases if you use lanterns in windy conditions.
