Lieutenant José A. Quiñones was a Peruvian pilot during the war.

In April, the State Department awarded a contract to a Maryland-based aviation company, Arinc Inc., to help train Colombian and Peruvian pilots and manage the operation, officials said.

But the final decision on whether to direct fighter planes to fire on suspect aircraft would be with the Peruvian and Colombian pilots.

A twin-engine plane struck a building in a Lima suburb, killing the two Peruvian pilots and eight Americans aboard, the United States Embassy said today.

The Customs Service and C.I.A. also began to fly smaller Citation surveillance aircraft to help Peruvian pilots intercept small planes.

Peruvian pilots trained by Americans fly them, with a D.E.A. official accompanying each flight.

The Americans did not recommend going to what is called phase 3, under which a Peruvian pilot begins a series of steps to try to identify the other plane.

And, referring to the Peruvian pilot, he asked: "Why didn't they call and check the registration?

But his brother, Gordon Donaldson, an osteopath in Morgantown, Pa., questioned why the Peruvian pilot and American monitors of Peru's drug interdiction efforts had not recognized the missionary plane.

Alejandro Velasco Astete (* Cusco, September 23, 1897 - September 28, 1925) was a Peruvian pilot, most recognizable for being the first man to fly over the Andes.
