And spends ???K making 5 passes?! I'm guessing it takes in the neighborhood of 30 to 40K for travel, parts, fuel and wages not to mention the upkeep on support equipment. Going out the first round is never a money maker no matter how much fun it sounds like.
In 1968-69 we figured it cost around 400.00 on average to go, stay and get home in one piece. That included maintaining the tow vehicle and trailer. Once we were there we spent about 150.00 a round if we didn't break too much stuff. If we destroyed a motor, I seem to remember if we bought/built a complete new bullet it cost about 3300.00, but that was everything including the spark plugs.
