NASA's research plane, the WB-57, made an emergency landing on its belly after a mechanical issue, sending sparks flying. The incident occurred at Ellington Field in Houston on Tuesday, with the aircraft en route to a routine training flight. The crew, both NASA employees, were safe and underwent medical evaluations, clearing them to return to good health. The WB-57, a mid-wing, long-range aircraft, has been conducting research missions since the 1970s, known for its reliability and customer-oriented service. The incident is under investigation by NASA and the Federal Aviation Administration to determine the cause of the mechanical issue. Despite the incident, NASA reassures that Artemis II operations will not be impacted, as they have multiple aerial assets available for support.
