An experimental aircraft was forced to land without landing gear Sunday afternoon at the Prineville Airport. Prineville dispatch got a call after the plane had landed reporting this incident. When emergency units arrived, they found the single-engine plane had run off the runway during the landing and that the pilot had been unable to lower the gear prior to landing. The pilot was not injured. According to FAA files, the plane is registered to Vernon Goodsell, of Sisters. When he flipped the switch to lower the landing gear on one of those unique planes, an XP-Talon, on approach to the, he figured it had extended as it’s supposed to.  But this time, for whatever reason, it didn’t, as he learned on touchdown.  Instead, Goodsell’s plane made what the calm and quiet pilot later called a “gear-up landing” others might call a crash-landing, and ran off the runway.  “I thought (the gear) was down, came in, hit the pavement and kept on skidding,” he said.
