(CNN) -- Don't underestimate the power of a spilled cup of coffee. A United Airlines flight from Chicago to Frankfurt, Germany, was diverted to Toronto this week after the pilot dumped a cup of coffee on the plane's communication's equipment. The unwanted liquid triggered a series of emergency codes, including one for a hijacking, according to Transport Canada, the agency that regulates transportation in Canada. "With the help of their company dispatch staff, the flight crew was confirmed the problem to be a NAV(navigation)/communication issue and not a valid code 7500 (for a hijacking or unlawful interference)," Transport Canada said on its website.
