Clinton grounded by radar failure

Sen. Hillary Clinton was stuck in Little Rock, Arkansas Tuesday after appearing at an event there with her husband.

CHICAGO (CNN) – Sometimes it doesn’t matter who you are – even presidential candidates can’t overcome air travel headaches.

Like thousands of other travelers, Senator Hillary Clinton, D-New York, found herself stuck on the tarmac Tuesday. She was grounded in Little Rock after a communications line failed, knocking out radar and telephone service to the Federal Aviation Administration’s Memphis Center.

The delay forced her to cancel an appearance at the Change to Win union convention in Chicago, where she was to deliver an afternoon address. Instead, she spoke to the gathering by phone, explaining she was still on the tarmac. Fellow Democratic candidates Barack Obama and John Edwards spoke to the convention earlier in the day.
