Millions of dollars later, Congress has effectively killed a military plane program the Pentagon repeatedly rejected, and which never had a successful flight. The $63 million Congress poured into the DP2 program over 20 years was not requested by the Department of Defense. Instead, it was mandated through obscure provisions in bills known as "earmarks." Most of those earmarks for the DP2 were inserted by Rep. Duncan Hunter, R-Calif., in whose district the plane was designed and built, in prototype. The 2008 defense spending bill does not include an earmark for the DP2. Hunter had wanted to direct $6 million toward the plane’s development.

"One-third of our present vertical takeoff aircraft have crashed," he said by phone from Texas, where he was campaigning for president. "Continued research and development of the DP2 is warranted." The DP2 project was the subject of an ABC News investigation in June and a calamitous congressional hearing. Click Here for Full Blotter Coverage. Designed as a plane that can take off straight up and then fly at 700 miles per hour, the DP2 has never attained a height of more than a few feet in prototype tests before crashing to the ground. The experimental plane was panned by most of the government engineers who were assigned to review and manage the project. The plane’s creator, Anthony DuPont, has donated $36,000 to Hunter’s congressional campaigns. Hunter has denied the contributions had any connection with his continued support of the aircraft. He said he makes "decisions on what I think is right for the country," and that he has rejected other projects backed by large campaign contributors, like General Dynamics and Boeing.
