A Cessna Citation II (CE-550) departing just before a thunder storm moves over the airport. As we taxi the aircraft to the runway you can see the shelf cloud of the approaching storm. This was an empty flight where we were doing some flight training so you can hear discussion of speeds to use and technique. The Citation is a probably on of the easiest jets to learn to fly. During the visual approach we pick up some light rain and the landing is on runway 2C at the Nashville International Airport (KBNA).
