Ukrainian airspace has been closed to air traffic since the full-scale invasion by the Russian Federation on February 24, 2022. Boryspil International Airport (KBP / UKBB), located near Kyiv, suspended all routine operations immediately following the start of hostilities, and routine and general flights remain suspended. This market will resolve to "Yes" if at least one manned aircraft successfully lands at or takes off from Boryspil International Airport between market creation and the specified date, 11:59 PM ET. Otherwise, this market will resolve to "No". Eligible flights include any manned fixed-wing aircraft or rotorcraft (helicopter), regardless of registration, owner, or purpose (e.g., commercial passenger, cargo, military transport, diplomatic or state flight, technical ferry, or emergency landing). Unmanned aerial vehicles (UAVs, drones, or loitering munitions), touch-and-go passes without a full touchdown and stop or taxi, and landings or departures occurring outside the physical boundaries of Boryspil International Airport will not count toward the resolution of this market. The primary resolution source will be verified radar and ADS-B flight tracking data (e.g., Flightradar24, ADS-B Exchange) and official announcements from Boryspil International Airport, the State Aviation Administration of Ukraine, or the Ministry of Infrastructure of Ukraine; however, a consensus of credible reporting will also be used.
