Before leaving, the scientists decided to test the equipment they would use to detect airborne nitryl chloride on the cruise by sampling the air in Boulder, a mile above sea level.

Huge as it is, the LHC doesn't look too impressive from the air since the actual 17-mile (27 km) tunnel lies buried an average 330 feet (100 meters) underground.

You're paid by the mile and then give money for air transportation back home.
