Doubtful, but who knows for sure. The pylons and control surfaces would need major work. along with engine changes I would assume.. .. .I do know that they have converted DC-9s that can deploy the thrust reversers in flight and hang at a very steep angle of attack without meeting redline. It's getting them used to the steep angle of attack is what they are after not the speed. <img border="0" title="" alt="[Big Grin]" src="biggrin.gif" />
