Why pilots knew about Ottawa's surprise fireworks but neighbours didn't

Ottawa surprised residents with a fireworks show on July 10 using leftover Canada Day explosives. Pilots received an official three-day warning; the public got none. Thirty-eight residents complained, and two city councillors were left in the dark. The mix-up shows airports and city government didn't talk to each other about alerting people—even though launching the fireworks was actually the right call.
