United Airlines confirmed that a Boeing 757-200 lost a wheel after taking off from Los Angeles but landed safely in Denver, causing no injuries to the passengers or crew. This incident marks the latest safety concern for Boeing, following recent incidents with United Airlines and Delta Air Lines. This is the second time in recent months that a United Airlines Boeing plane has lost a wheel after take-off. Boeing, under increased scrutiny after the 737 Max crashes, has agreed to plead guilty to fraud in a settlement with the US Department of Justice. The 757-200 aircraft involved in this incident was delivered 30 years ago, showcasing the aging fleet of some airlines. The Federal Aviation Administration is conducting an investigation into what caused this wheel loss.
