Blue Origin founder Jeff Bezos speaks in front of his company's New Shepard suborbital vehicle on display at the 33rd Space Symposium in Colorado Springs April 5. Bezos said the company still plans to start flying people on suborbital space tourism flights by the end of 2018, although the company has yet to start selling tickets or even setting a ticket price. Development of New Shepard, he said, is informing the company's plans for an orbital launch vehicle, New Glenn, that will use the same BE-4 engines that United Launch Alliance is considering for its Vulcan rocket.
