Donald J. Trump has a net worth of anywhere from $4,000,000,000 to $10,000,000,000, depending on fluctuating real estate and other investment valuation. His air fleet includes a Cessna Citation X jet, three Sikorsky S-76B helicopters, and a Boeing 757 jet. Trump’s 757 is three times the size of the average private jet and every inch of it is customized to meet his high standards. Outside, it’s powered by Rolls Royce engines. Inside, it has gold seatbelts, high-grade leather seats, a master bedroom, and even a shower. It’s a smooth ride for passengers, but for pilot John Dunkin, things can get turbulent in a hurry, especially when one of the jet’s most vital parts goes missing.
