A rule of thumb is the person has have a net worth of at least five times the cost of the aircraft.
(Or have a very long thumb.
)
Is what is was basing this on, not my logic someone else's.
I don't see why it's weird or unusual to wonder how rich someone is if they can afford a jet that's worth $50 mil, the reason being is that i don't wanna go for a job with someone who's not worth anythin and therefore an unsecure move.
