Who: United Airlines
What: A flight from Chicago to Germany carrying 241 passengers was forced to make an emergency landing in Canada after a pilot spilled coffee on the plane’s radio equipment.
Why it’s outrageous: The airline refused to confirm that spilled coffee triggered the problem — the detail was noted by the Aviation Herald, a website that logs incidents on commercial flights based on flight data and incident reports. It was reported that the crew advised of communication problems, then reported it had navigation issues as well. The crew cycled through the transponder codes for unlawful interference and loss of communication. After contact with the company, the FAA reported that the pilot in command had spilled coffee over the radio equipment, which interfered with the communication equipment. He inadvertently sent an unlawful interference code, then changed to the loss-of-communication code.
