The chief executive of United Launch Alliance said Thursday evening that his company now plans to fly its Vulcan rocket for the first time this May. While acknowledging that additional delays are always possible, Tory Bruno even put a date on the launch attempt—May 4.
In a wide-ranging teleconference with reporters, Bruno discussed the development of the next-generation Vulcan rocket, his plans for this year, and the future of his company.
