Multiple explosions rocked the north of Toronto, Canada in wee early hours on the morning of August 10, 2008.  A huge explosion was followed by numerous muffled ones at the Sunrise Propane Industrial Gases, a propane company located near an airport and in the middle of a residential neighborhood.

One resident 10 km away from the explosion said his house shook and the sky rumbled every few seconds. Houses nearer to the explosion had their windows blown out and had their doors fly off their hinges.  The shaking was so strong that one person thought a car had crashed into his house.  A woman said a force picked her up and threw her from her bed. A hissing sound was heard. A man saw a huge fireball and said a "wave of a heat" followed him, as he ran out of his house.  Some describe the heat as a tidal wave of fire.

Balls of vivid orange fire rained from the sky as a huge mushroom cloud and black smoke filled the air with an acrid smell.  Some people drove themselves to the hospital complaining of respiratory problems.  60 people had minor injuries, 12000 people were evacuated from the area.  One fireman died from a non traumatic disorder, and one body was discovered which may or may not belong to a missing employee of the propane company.Pieces of metal from the propane tanks landed kilometers from the site.  What remained after the fire was put out looked like a war zone.  

Now we can compare this incident with other similar type of incidents.  What is interesting is that there is visible evidence to implicate ball lightning.  Mostly ball lightning is invisible, but this time, perhaps because of the propane, is visible and seeing is believing.  Watch following videos.  There is a split second worth of a shock wave followed by the growth of ball lightning into a ball which slowly disappears.  Compare this video of the incident with ball lightning experiments in the lab and in a microwave.
