Crew and passengers vomit mid-flight: Third mystery illness incident in two months

A United Airlines flight from Houston to Boston was diverted to Washington D.C. due to a "biohazard" situation caused by a sick passenger. The incident led to crew members vomiting and passengers requesting masks. The plane landed safely, and no medical attention was required for the 155 passengers and six crew members. The aircraft is undergoing a deep clean before resuming its journey. Similar incidents have occurred recently, highlighting the need for stringent in-flight health and safety measures.
