Alec Baldwin has mysteriously vanished from Twitter after using the social networking site to badmouth American Airlines. The 30 Rock star was fuming after he was ejected from a flight from Los Angeles to New York on Tuesday for using his cell phone on-board. He began to lay into the floundering airline in a series of tweets, one in which he likened American's flight attendants to famously-strict "Catholic school gym teachers from the 1950′s." However, by Wednesday, all of the disparaging posts had been deleted and Baldwin's name on his profile changed to the word "Deactivated." Many of his 600,000-plus subscribers had "unfollowed" him as well. News of Baldwin's blowup swept the Internet in real time, as passengers on Baldwin's flight tweeted what they saw. Baldwin himself quickly took to Twitter to explain what happened, claiming he was playing a game of Words with Friends while the aircraft was parked at the gate, waiting to take off. In a later statement released via The Huffington Post, where Baldwin often writes guest commentary, the actor elaborated that he was rudely singled out, as other passengers were using their mobile devices without repercussion. He apologized to his fellow passengers for his actions, but not to American Airlines. AA recounted a very different version of the incident. A post on the company's Facebook page alleges Baldwin cursed at the flight crew and snuck into the lavatory to continue using his phone, in blatant disregard of the "fasten seat belt" sign. Baldwin denies the claims.
