Documented aircraft involved in today's chemical & biological attack on the UK via the UK government's TERRORISM blessing.
The sky over London has been a complete chemical white-out since 11:00am with relentless dumping of toxic nano particulates via aircraft every few minutes.
Average cloud height in the UK is between 3280 to 6560 feet.
Contrails form at between 25,000 to 40,000 feet.
So when you see 'contrails' below the clouds in the UK, they are in fact Chemtrails which are attempting to block out sunlight.
These Chemtrails contain barium, thorium, caesium and other such poisonous materials.
The practice needs to be banned, yet Ed Miliband has given the go ahead for even more.
