The Civil Air Patrol and area police agencies were searching the Wasatch canyons Friday for a missing small airplane that left Salt Lake International Airport Thursday evening with a student pilot and instructor aboard.

Lt. Bob Smith, flight operations officer for the CAP's Utah Wing, said the Cessna 152 had not been seen since it left the airport at 5:30 p.m. Thursday for a cross-country training flight to Park City and back.Smith said two CAP planes began the search at 2 a.m. Friday. At daybreak, two more planes joined in, as did sheriff's departments in Utah and Wasatch counties.

Smith said the search was concentrating on flight paths from Salt Lake City to Provo, and to Heber, Park City and through Parleys and Emigration canyons back to Salt Lake City. He said names and addresses of the student pilot and instructor were unavailable, but they were believed to be from the Salt Lake area.
