Question

"Audio telescope" could save planes from birds An "audio telescope" that can identify different species of bird by their calls could soon help protect planes from crashing. When planes collide with birds, the results can be catastrophic - an event most likely to occur on lower-altitude flight paths near airports. Radar and in- frared detectors can already spot birds but cannot tell a large bird that could cause serious damage from a small, low-risk one. "Bird strikes are a significant cause of plane crashes, particularly for small craft." says Vincent Stanford of the US National Institute of Standards and Technology (NIST) in, Maryland, US, who is developing the system. According to the US Federal Aviation Administration, bird strikes have caused $ 2 billion of damage to US-owned aireraft since 1990. The species of bird that a plane hits can make a big difference to the amount of damage caused. For example, a hefty Canada goose poses mcre of a threat that a smaller, lighter gull or hawk. An “audio telescope" is used to pick the sound of distant birds. It turned out to be very successful at discriminating between different birds. •Find the mistakes. Write the correct answer.
