US Republican vice presidential candidate, Ohio Senator James Vance encountered an emergency when he was flying from Milwaukee, Wisconsin to Cincinnati, Ohio on August 16 local time, and returned to Milwaukee for an emergency landing. It is reported that Vance was on a Boeing 737 aircraft that day. The reason for the emergency appears to be a malfunction of the sealed hatch, but the plane was able to land normally without an accident. A week ago, former US President and Republican presidential candidate Trump was on his way to Bozeman, Montana, when the plane suffered a mechanical failure and temporarily diverted, and finally landed in Billings, near Bozeman.
