FILE- In this Dec. 13, 2011, file photo Microsoft co-founder Paul Allen looks across at a model of a giant airplane and spaceship he plans on building, during a news conference about the plane in Seattle. Prior to his death on Monday, Oct. 15, 2018, Allen invested large sums in technology ventures, research projects and philanthropies, some of them eclectic and highly speculative. Outside of bland assurances from his investment company, no one seems quite sure what happens now. (AP Photo/Elaine Thompson, File)
