These oddly colored aircraft flew into the Airshow at Ukiah, California. They taxied up and parked and they had strange shades of green and red and the other was tiger striped. Apparently these were not enemy aircraft, but aircraft made by China for their Airforce in 1969. They weighed 3,000 lbs and cruised at 145 MPH. They had a 9 cylinder 285 hp engine. Their name was “Nanchange”.
