Back in the mid 70s, I had a 60s era Jaguar XKE convertible. It had two exhaust pipes coming out the back that were tuned. Each time I fired it up, it was a rush and had a sound I have trouble describing. Around that time, I also became a member of the Confederate Air Force. They were working out of a couple of hangars off of Hwy 6, north of I-10 in the far west side of Houston. They called it the West Houston branch of the West Texas Wing.( So what if we were in sout EAST Texas. Sort of like the joke about a Confederate Air Force formation was at least two aircraft going in the same direction on the same day) Regardless, I helped do a top end job on a Rolls-Royce Merlin that was in a P-51D mustang. ( I think back and cry. It was for sale at the time for $275,000 with a spare motor. It was airworthy and headed for Reno) After we buttoned her back up, we rolled her out to the tarmac and hooked up an external battery cart. Then the pilot moved the starter switch and turning that big screw. It took a few minutes to get the Merlin to fire up, with flames coming out of the different stacks. There was a lot of smoke and various flames coming out of each of the twelve exhaust stacks. Finally she catches, the screw speeds up, the roar increases. She settles down and runs smoother. It was an incredible sound that you could feel. The chief mechanic leans over and shouts into my ears, over the roar and says "You know, when these things fire up, it's better than sex!" I have to agree. I will never turn down an opportunity to fly in one. Heck to jsut crawl over one or sit in the cockpit. It reminds me that regardless how I may feel about Tom Cruise, I have to admire him and I am somewhat envious because I have read that he owns tow P-51s. Sort of like John Travolta having a Gulfstream and Boeing 720C. He keeps both at his house in Florida, or at least the photographs from that particular day showed it that way.
