Hope I'm not proven liar: SpaceX exec on manned mission date
On predicting SpaceX's first manned mission date, President Gwynne Shotwell said, "I hope I am not proven to be a liar on this one." "Predicting launch dates could make a liar out of the best of us," she added. Shotwell had said an unmanned flight to the ISS in November would pave way for a manned mission in April 2019.
