This market will resolve to "Yes" if a Boeing plane is forced to make an emergency landing in the United States due to a possible technical or mechanical issue between March 20, 4:00 PM ET and March 31, 11:59 PM ET. Otherwise, this market will resolve to "No". For an emergency landing to qualify for a "Yes" resolution, the Boeing aircraft must make an emergency landing within one of the 50 US states or Washington D.C. Note - emergency landings due to passenger issues (such as a passenger opening the door mid flight) will not suffice to resolve this market to "Yes." If the plane makes an emergency landing due to a possible technical/mechanical issue it will suffice to resolve this market to "Yes." The resolution source for this market will be a consensus of credible reporting.
