What's worse than a drunk pilot? An alcoholic drunk pilot preparing for a 9 a.m. transatlantic journy.

A United airlines pilot was arrested in the cockpit of his plane on suspicion of being drunk before take-off Sunday morning. The 44-year-old man was led off the plane by police following a breath test at Heathrow Airport's Terminal 1.
The flight was headed to San Francisco.

Police became involved after being tipped off by a member of the airport's ground staff, who suspected the pilot had been drinking before the 5,300-mile flight.

The legal limit for pilots is nine micrograms of alcohol in 100 millilitres of breath - more than three times stricter than the drink-drive limit which is 35 micrograms. Whatever that means. NO ROBOTUSSIN!
