I have found an old report which I made back in 2009 ( thinking that we were witnessing UFO activity when it was nothing more than parachute flares) .
For anyone who is interested in the chemical structure of a flare then here it is:
Flares produce their light through the combustion of a pyrotechnic composition. The ingredients are varied, but often based on strontium nitrate, potassium nitrate, or potassium perchlorate and mixed with a fuel such as charcoal, sulfur, sawdust, aluminium, magnesium, or a suitable polymeric resin.Flares may be colored by the inclusion of pyrotechnic colorants.
And here is an declassified Military Document to prove to you that there are such things as floating flares .
and full specifications for parachute flares:
Below is what we call the unexplained balls of light . This one was captured at Guys Cliffe House in Warwickshire and almost at ground level , not in the air. The appearing ball of light first became apparent by a flash of light then slowly but surely appeared as a bright ball of light which then turned into something very odd which resembled a snaking light ! Explain this please !!
