A centennial celebration of the first airmail delivery by the U.S. Postal Service was canceled Sunday.

A plane was supposed to land at the American AirPower Museum in Farmingdale to remember the date. An issue with the plane and the weather forecast forced the event to be rescheduled.

The manager of the museum says the first plane of the U.S. Postal Service carrying mail flew from Maryland to Belmont Park on Aug. 12, 1918.

A reenactment of the event was supposed to include a 100-year-old biplane making a trip from College Park, MD to Farmingdale.

Larry Starr, of the American Airpower Museum, says it's important to remember the start of airmail because it is still a big part of society.

"Mail will always be important no matter what digital media is," Starr says. "You need hard copies of things, packages that can't go through computers."

The Postal Service also issued special stamps for the 100-year anniversary.
