Tin Cup is a 1996 movie about a washed up driving range golf pro (Kevin Costner) who attempts to qualify for the US Open. Costner just needs to play nine more holes to qualify when he gets into an argument with his caddy (Cheech Marin) and ends up snapping all of his clubs in half - - except for a seven iron. Being a Hollywood movie, Costner proceeds to shoot par on the back nine using nothing but his seven iron. Later, a somewhat drunk Costner encounters a long time rival (Don Johnson) in a bar and crows about shooting par on the back nine using only a seven iron.
Costner challenges Johnson as to whether "he has ever done that.""No," Johnson admits "and actually it had never occurred to me to even try."
About a week ago we rented Tin Cup at Blockbuster and while watching the movie the foregoing scene reminded me of an extended discussion over at Space Cynics as to whether ticket revenue from suborbital passengers will be sufficient to offset the capital costs of building $225 million spaceports. The Cynic author is of course skeptical.
I honestly do not know whether anyone can fund a suborbital spaceport solely from ticket revenue collected from paying passengers. My gut says "No!" but I could well be wrong. Whatever. But the larger issue the Space Cynics essay raises is similar to the challenge of playing golf using only a seven iron. Maybe you can win with just a seven iron and maybe not, but the question still stands, why even try?
Just as Nevada Bob's offers a wide variety of clubs, spaceports such as the ones to be built in New Mexico, Singapore and Dubai should be able to harness a large number of diverse revenue sources in addition to revenue from paying passengers. To be fair, Space Cynics does mention some of these alternate revenue sources yet only in passing and instead proposes suborbital point-to-point as the one true killer application.
Whatever. Playing golf with only a five iron is hardly superior to playing golf only with a seven iron.
