No, I have no idea. I have a wealthy friend who tosses her moeny around, but she even decided against NetJets and she has five children, with three of them under the age of five and they do a lot of traveling between their on shore and offshore homes.
For a small plane that never leaves the ground it is over $10,000 a month. If you actually use it you have just bought a luxury car.
OMG, just shoot me!
