First of all, this is a tough racket, period. You must have more than a good business plan; you must have a genuine formula for success, and even then... You need contacts, contracts, connections, money, lots of money, Etc. Ad nauseum. Also luck, don't forget luck... Much of the projected US ultra light jet market has waned due to circumstances effectively beyond its control [economy, globalization, politics, blah blah...] That market was small business owners, a majority of which were expected to be the traditional self made variety, with the types of businesses doing 10 Mil a year or so. Much of that base has been decimated. Therefore I would think the ultra light jet provider segment would be somewhat saturated at this point, to begin with. Basically the operators who will be successful with these size jets in the US will primarily be the folks who already are. The manufacturers need a global market to be successful. Not trying to dissuade you, just make sure you know the score before getting in too deep.
