Gulfstream Aerospace said the two fleet-leading G150s, which are both owned and operated by a U.S.-based multinational energy company, recently combined to surpass 10,000 flight hours. This achievement was accomplished without incident and took only five years, Gulfstream noted. The midsize business jet entered service in August 2006, and some 100 G150s are flying with operators in the U.S., Canada, Central America, South America, Europe and Asia. The entire fleet has accumulated more than 130,000 flight hours and more than 90,000 landings.
