Two men were injured yesterday during an explosion at a gas plant in Gillette, Wyoming.

The Campbell County Fire Chief says it happened at Thunder Creek Gas Services.

The brother of one of the victims says he was working with a trainee when pressure built up in a valve.

Both men were air lifted to the burn center in Greeley, Colorado.

The man's brother is in stable condition but was badly burned on his hands and face.

The other man is said to be in critical condition.
