At least 300 service members were slated to participate, primarily from military bands and drill teams, but that number could rise as additional military aircraft and other flourishes are added to the event.

The Defense Department and the National Parks Service have not yet determined whether they can accommodate all of Trump’s requests, nor what they might cost. The Post reports that the F-35 costs about $30,000 per hour to fly, and each Blue Angel jet costs at least $10,000 per hour to operate. Operating Air Force One costs some $140,000 per hour. And then there is the cost of repairing the city’s roads, which experts fear would be damaged by armored vehicles that could weigh in excess of 60 tons—a problem the Pentagon has pointed out before. (Officials are currently weighing the option of having tanks on static display.)

Beyond the cost overruns, there is the logistical and administrative mismanagement that stems from the president appointing himself producer. The Post reports that the White House never implemented a distribution system for dispersing the VIP tickets it had planned to release, nor a system for getting guests through security. More importantly, no one quite knows how much this parade will end up costing—a pertinent point, considering that the last attempt at a military parade was scrapped after its $92 million price tag was leaked. But one thing is for sure: The fireworks will be classically Trumpy—twice as long as last year’s display, costing twice as much, and with new, over-the-top patriotic elements, “including a massive American flag and the words ‘U.S.A.’ spelled out in the sky.”
