An American Airlines flight attendant was arrested while giving a safety demonstration on a flight from Manchester airport after she was found to be eight-times the legal alcohol limit. Stacy Rosehill, 57, from Chicago, was carrying out the pre-flight demonstration ahead of the American Airlines flight to her hometown when officers were alerted to a tip-off by security staff, who could smell alcohol on her breath. The senior flight attendant was then escorted off the Boeing 787 Dreamliner and taken into custody as around 300 passengers were waiting to take off. Tests later showed she had 71 microgrammes of alcohol per 100ml of her breath. The legal limit under aviation rules is 9mg, much stricter than the rules for driving. Yesterday Manchester Magistrates Court heard the incident occurred on October 28 after Rosehill had been out with friends for dinner to a venue where diners provide their own drinks and "miscalculated" the amount she was drinking. She then had a miniature whisky from her hotel at 2am to help her sleep, before arriving at Manchester Airport. When she reported for duty seven hours later, she was still under the influence.<br/>
