2 a large plane for carrying passengers:
a commercial/commuter airliner
Certainly, the pilot wouldn't be circling around Georgia and Alabama for an hour, buzzing airliners.
Three days later, a Chicago and Southern airliner crew saw a fast-flying disk near Stuttgart, Arkansas.
Such a situation is dangerous not only for ships but for airliners too.
But change the setting to a foreign airliner.
Getting timing right is always a matter of great moment for flying airliners, and it is something to which and can contribute.
In the circum stances, the air traffic controllers would have had no way of knowing that the airliner was in fact off course.
