Court rejects pilots' appeal to age 60 rule

ASSOCIATED PRESS
    The Supreme Court yesterday declined to hear a pilot group's challenge to a federal rule forcing them to retire at age 60.
    Justices let stand a lower court ruling in favor of the Federal Aviation Administration, which says the retirement rule for commercial pilots is necessary for safety. Officials have argued that pilots lose critical cognitive and motor skills as they age.
