A Peruvian jetliner crashed into the Pacific Ocean because workers forgot to remove duct tape they had put over key sensors while cleaning the outside of the plane, NBC News reported Monday.
The Aeroperu Boeing 757 crashed into the Pacific Ocean shortly after taking off from the Peruvian capital of Lima on Oct. 2. All 70 people on board were killed.
Workers had placed the duct tape over the sensors - which monitor air pressure and help track altitude and airspeed - while polishing the outside of the airplane, NBC said.
Minutes after the plane left Lima, pilot Erick Schreiber radioed that his instruments had failed.
“What’s happening? What altitude am I at? Why is my ground crash alarm on? Am I over land or sea?” Schreiber asked.
In the past 10 years, at least 12 Peruvian planes providing commercial service have crashed in Peru.
