True we need to get back on topic!
Are you talking about the McDonnald Douglas XP-67? If so, I think it was a good design and had potential. It carried one heck of a punch too. If the prototype had not caught fire, it may have gotten somewhere. I think the end of the war though pretty much ended its chances.
