TYB
Up out of Houston Hobby Airport we have a Gulfstream 5 cruisin over the Gulf of Mexico at 45,000 feet. Ownership is Bank of Utah Trustee so a blind avenue there discovering ownership. But there is the paint job to consider. Either the owner is paid to use his jet as a billboard. Or it belongs to Sandals Resorts International.
