I didn't see this at all on the news, although I was only watching Pearl.
From Chosun Ilbo, can't post links yet, but a quick google search for "defecting north korean mig" shows some news results.A North Korean MiG-21 fighter jet crashed on Tuesday afternoon in the northeastern Chinese province of Liaoning. The Soviet-era plane crashed into a farm area in Lagu Township in Fushun Prefecture, about 200 km north of the border separating China and North Korea. The pilot died on impact.
China's Xinhua News Agency did not say which country the fighter jet came from or whether the pilot had died, but photos of the scene of the crash apparently taken by a Chinese resident and posted on the Internet showed a North Korean flag on the tail of the plane. Japan's Kyodo News cited Hong Kong media reports as saying the pilot died and the copilot escaped by parachute.
