Agaricus, I presume you kept my links given on the previous thread which gave examples of the F-8 (not Bearcat but Crusader) flying with wings folded. Regarding the title to this thread the F-108 was a proposed USAF Long-Range Interceptor and later proposed as a escort fighter for the B-70. Only a mock up was built.
