Quiet Bird: Boeing’s secret 1960s stealth plane concept
Boeing has decided to reveal a little secret from the past. The aircraft manufacturer has recently revealed their super-secret 1960s stealth plane experiment: the Model 853 ‘Quiet Bird’, a US Army observation airplane study.
What is sometimes called “invisible” aircraft is actually visible to the naked eye but can’t be caught on radar. This means that the aircraft can enter the airspace of a country without being traced, allowing for “stealth” attacks. Boeing’s ‘Quiet Bird’ was one of the first test studies of this kind of aircraft, which in later years would be intensely explored to create a number of aircraft such as the F-22 Raptor fighter and the B-2 Spirit bomber.
