Salute!
Tyler's site (
The War Zone - The Drive ) has been fairly reliable about many things and they had a source that agrees with my personal scenario of the "Spruce Goose" flight, thence to a museum.
Another source
told Reuters that Judy Allen, chair of Vulcan, a trustee of the Paul G. Allen Trust, and Paul Allen's sister, had let the flight occur to honor her late brother's wishes, but had already decided to close down Stratolaunch afterward by that point.
OTOH, Sierra Nevada might be able to use the beast for its Dream Chaser if they mate a suitable booster to it. The ISS supply mission payloads are small compared to the DoD and comm satellites.
Gums sends....
