A Dutch Air Force F-16 had a close encounter with its own cannon shells in January.

The Netherlands’ Defense Safety Inspection Agency (Inspectie Veiligheid Defensie) is investigating an incident during a January military exercise where a Dutch Air Force F-16 was ruined by live fire by a 20-millimeter cannon–its very own 20-millimeter cannon. A minumum of one round fired from the aircraft’s M61A1 Vulcan Gatling gun struck the aircraft as it stopped at targets on the Dutch military’s Vliehors range on the island of Vlieland, according to a report by the Netherlands’ NOS news service.
