Another trivia story. A gas company in the southwest knew that they had a leak in their natural gas line and put out a bid for contractors to find the leak for them.
Many of the bids came in with high prices due to the expensive equipment needed to detect the gas and the labor involved in tracking hundreds of miles of pipeline. The winning bid was significantly lower than all the others.
The bidder knew that since natural gas has no odor, the gas company adds a chemical to give it the smell of rotting flesh. They deem that this scent is most likely to be picked up by the human nose in even very small quantities.
It can also be detected by vultures in even smaller quantities. So the contractor simply drove along the pipeline until he came across a flock of vultures circling about it.
