The modified Boeing 727 generally soars to 32,000 feet at a sharp angle and then plunges 8,000 feet so passengers can experience 25-second snippets of zero gravity during the descent. Zero Gravity will pick up the bill, which normally is $3,750. The company also plans to have two seats on the flight auctioned off by two charities.'
