The Globe and Mail reports in its Tuesday edition that the chief executive officer of United Airlines says that a slew of frightening incidents will cause the airline to review its safety training for employees. An Associated Press dispatch to The Globe quotes Scott Kirby saying that the airline was already planning an extra day of training for pilots starting in May and changes in training curriculum for newly hired mechanics. In a memo to customers on Monday, Mr. Kirby tried to reassure travellers that safety is the airline's top priority. Mr. Kirby said the airline is reviewing each recent incident and will use what it learns to "inform" safety training and procedures. Earlier this month, a United flight returned to Houston after an engine caught fire, and a tire fell off a United Boeing 777 during takeoff in San Francisco. To a degree, United may be a victim of heightened concern about air safety since January when a panel blew off an Alaska Airlines Boeing 737 Max at 16,000 feet above Oregon. "I don't see a major safety issue at United," said John Cox, an airline safety consultant. "The media is enhancing the events with extra scrutiny. Anything right now that happens to a United airplane makes the news."
