I just heard the story of over 24 nursing home patients dying in the bus accident. They said that so many were on oxygen that this contributed to the problem.

Yes, from what I heard, the brakes on the bus sparked some sort of fire underneath it and as the tips of the flames reached up into where people were sitting the oxygen that was filling up the bus just ignited everything and there was a huge explosion. Pretty awful. I think 24 people died.
