Tracker is too modest to note it, but his extraordinary service to this country has involved more hours of up-close-and-personal experience with Zunis and A-4s than he may care to recall.
The A-4, in my view, is one of the best looking warbirds ever designed, right up there with the Spitfire and the P-51 Mustang. It was sometimes called "Scooter", "Tink," or "Heinemann's Hot Rod," after its designer, Ed Heinemann at Douglas Aircraft Co. Subject to correction, I believe it remains the smallest attack aircraft ever adopted by the Navy for carrier service -- small, beautiful, sleek, and deadly.
It occurs to me that those last four words might also be used to describe the R9.
