Lt. Col. Peter Fesler, 27th Fighter Squadron F-22A Raptor pilot, arrives at Base X during an Operational Readiness at Exercise Langley Air Force Base, Va. The surface of the Raptor resembles a normal paint job, but low observable technology minimizes the aircraft's radar signature, making the Raptor undetectable to enemy radar.
