There are Satmar businessmen who own or rent private jets. What’s more, you can buy a jet, lease it out, and it comes out almost free for your own use. I know several people who do just that, and if I did not fear flying in non-commercial airliners I’d probably look into this as a business venture myself.
Rest assured that none of the pennies you throw in a Satmar Bikur Choilim pushka, if those still exist, will go to pay for a private jet or use thereof. That is assuming the private jet story is even true. If it is, a private donor will pay for the jet.
