The first time retired computer engineer Jack Clemens tried to build a scale model of the USS Macon, a helium-filled naval airship lost in bad weather in 1935, his cat jumped on the prototype from a high shelf and ruined the hull. Clemens finished a second version in 2008 but totaled it during an unexpectedly windy test flight. Finally, in April, Clemens completed version number 3, a 20-foot-long radio-controlled replica accurate down to practically every detail, from the airbag to the propellers.
Hangar One's behemoth structure once housed airships such as the doomed U.S.S. Macon, and is so large that clouds can supposedly form and rain inside it. Now NASA and the U.S. Navy have promised to replace the hangar's toxic siding with a new Teflon-covered fiberglass fabric skin, The Register reports.
