Of course it will work: Watch
One can still get just about 4% interest these days. 4% on $1.5 billion is $60 million a year. The hourly cost of a Lear 60 including lease fees on say 750 hours a year is about $3,000. $60 million divided by $3,000 is 20,000 divided by 750 is 26.666. So they could operate 26 Learjets, not charge the customers a bean and STILL make a profit.
Easy init!
