Military planes will fly over four big cities Saturday afternoon to celebrate Independence Day in a lead up to the Fourth of July air show in Washington, D.C.

Defense Secretary Mark Esper approved the aerial salute to several cities that were instrumental in the American Revolution. The flyovers will start in Boston at 4 p.m. and then travel to New York City, Philadelphia and Baltimore.

The military planes will then join the larger air show in Washington, D.C., that will begin around 6:30 p.m. with a demonstration by the U.S. Army Golden Knights Parachute Team and a 21-gun salute by the military’s 3rd Infantry Regiment, known as The Old Guard.

President Trump is slated to make remarks at the White House afterward during a Salute to America celebration that he and First Lady Melania Trump are hosting for frontline workers -- including police, doctors, nurses and members of the military -- and their families.

About 1,700 service members will support the aerial celebration, according to military officials.
