Engineers prep a mockup CST-100 Starliner for landing tests.
A mock-up of Boeing’s CST-100 Starliner is seen as it is prepared for lifting as part of landing tests at NASA’s Langley Research Center in Virginia. The Starliner was dropped onto a pad of dirt to gauge how it behaved for landings on land as it will do during actual missions. Photo credit: NASA/Langley Research Center
