But that doesn't make sense either. It would have been impossible to keep the aircraft from public's eyes, considering the Chengdu airfield is in the middle of the city, and right beside residential complexes as you can see in the pictures.I actually think this exact plane has flewn with the domestic engine. I don't think the Chinese govn't would actually risk anything when they expect the world is watching. So I believe this plane has not only flewn before, but flew multiple times. It has flewn enough times and performed well enough to give the leadership the confidence to let it go public like this.
