Three vintage biplanes flying across the country in commemoration of the 90th anniversary of U.S. airmail service will make a stop in Salt Lake Wednesday.

The planes, which left Farmingdale, N.Y., on Sept. 10, are following the original transcontinental route used by pilots when airmail delivery began in 1918. Salt Lake was one of 15 stops for the early service.

One of the planes on its way to Salt Lake — a 1928 Boeing 40C — crashed into a mountainside south of Portland, Ore. in 1928 as the pilot attempted to avoid foggy weather. He survived the crash, but the sole passenger on the flight did not. The current pilot of the renovated craft, Addison Pemberton, speaking by phone Tuesday from North Platte, Neb., said that weather played a role in this anniversary trip when all three planes were delayed in the Midwest by rough weather caused by the aftermath of Hurricane Ike.

Pilots will show off their planes and speak to the public from 11 a.m.-1 p.m. Wednesday at Municipal Airport 2, located at 7365 S. 4450 West, behind Jordan Landing.
