When my daughter was a paramedic, she worked at a Fire Station near Dulles Airport in Virginia. One day they got a call from Dulles to extricate an unruly passenger from one of the international flights. Evidently, just as they were preparing to take off, the passenger was acting crazy and the pilot called the tower to get him off his plane.
My daughter and her partner got onto the plane and discovered that the flight crew and a few passengers had restrained the guy with duck tape. Wasn’t too hard to get him off and to the hospital, LOL.
She told me afterwards it was kinda cool to drive her ambulance out onto the runway.
They obviously failed to duct-tape the guy's mouth and nose.
