On October, 1996 Aeroperú Flight 603, bound from Jorge Chávez International Airport in Lima, Peru to Comodoro Arturo Merino Benítez International Airport in Santiago, Chile crashed into the Pacific Ocean, killing all 70 on board. Shortly after take-off the crew of the Boeing 757 were confused by false speed and altitude readings and contradictory warnings from the aircraft's air data system. The crew declared emergency and decided to return to departure airport. In preparation for an emergency landing the crew descended the aircraft, but relying on false reading, the crew went too far causing the aircraft to crash into the water. Investigation of this accident revealed that, the masking tape was accidentally left over static ports after the aircraft cleaning. This lead to false airspeed, altitude and vertical speed data and contradictory cockpit alarms (Wikipedia, 20112).
