A Palm Bay man was burned over 60 percent of his body when his fume-filled garage exploded.
A witness told Palm Bay police the neighbor was on fire when he ran from the garage.
Neighbors reported the explosion sounded like a train crash.
Three other people were inside the home when the explosion took place. They were not injured.
The man was airlifted to a burn center in Orlando late Sunday.
Police did not have an update on the man's condition. His name was not released.
