Open this cabinet's Cost of Space Travel file and you will find Dream Chaser already there - 2013, listed among the contenders, back when it belonged to SpaceDev. Thirteen years later it still has not flown. The spaceplane is built, tested, named Tenacity, demoted from an ISS docking to a free-flight demo, and waiting on a Vulcan rocket - late 2026, allegedly. The longest "almost" in commercial spaceflight. This file exists so that one day the stamp can change.
