  • mishap, n. military euphemism for a terrible crash

    Washington Post, 19 January 2016:

    Driving the increase was a mysterious surge in mishaps involving the Air Force’s newest and most advanced “hunter-killer” drone, the Reaper, which has become the Pentagon’s favored weapon for conducting surveillance and airstrikes against the Islamic State, al-Qaeda and other militant groups.


    These accidents are categorized by the military as Class A: mishaps that destroyed the aircraft or caused at least $2 million in damage.
