Bombardier's next generation $73 million Global 7000 private jet just made its air show debut

• Bombardier recently showed off its fourth and newest Global 7000 prototype private jet.
• The aircraft is expected to be one of the most capable and expensive private jets in the air with a price tag of $72.8 million.
• The 7000 has a maximum range of more than 8,500 miles. That means it can fly non-stop between Sydney and San Francisco or New York and Dubai or London and Singapore.

Last week, the long-await Bombardier Global 7000 made its air show debut at National Business Aviation Association (NBAA) Conference and Exhibition in Las Vegas, Nevada.

The Canadian plane maker showed off its fourth and newest Global 7000 prototype, the first with a complete interior. According to Bombardier, flight test vehicle 4 or FTV4 will be used to evaluate the Global 7000's passenger experience including its cabin management and in-flight entertainment systems.

"Our Global 7000 flight test vehicles continue to undergo rigorous testing at our world-class flight test center in Wichita, Kansas," Bombardier vice president of product development, François Caza said in a statement. "Having now flown nearly 900 hours, the aircraft continue to perform extremely well and to exhibit a high level of reliability."

"Areas of the flight envelope and the performance of the systems, including at extreme temperatures, have been tested. The results show a maturity which is in full support of the planned certification activities," Caza added.

Bombardier is currently preparing the fifth and final flight test vehicle at its factory in Toronto, Canada.

The long-delayed Global 7000, a victim of Bombardier's recent financial troubles, is expected to be one of the most capable and expensive private jets in the air with a price tag of $72.8 million.
