They had a PBS special about the Mig 15 vs the F-87 Sabre. The Mig had some advantages over the Sabre, but the Sabre was easier to fly. Also, the Migs would hold back till the Sabres were about out of fuel. I think Yeager flew a Mig against an American General in a Sabre. The General lost big time. Yeager told him it wasn't the plane. They switched and Yeager still kicked butt.
