He used to own another G650 (G-ULFS) but he sold the jet. All jets have the same logo on the tail. He also owned 2 Bombardier Global Express (G-LXRS) and (G-XRS).
The Gulfstream G650 is a twin-engine business jet airplane produced by Gulfstream Aerospace. In general the G650 is considered to be the best private jet money can buy.
The new build price for a G650 is approximately US$ 65 million, but customization can quickly increase the price with several millions.
