(WFAA/KDAF/CNN) – F-35 fighter jets, which are being tested at three bases, are being grounded because one jet developed a crack in its engine blade.
Supporters say think of the jet as a Swiss army knife for 21st- century warfare, so good the Air Force, the Navy and the Marines all wanted it.
The Pentagon plans to buy nearly 25,000 planes, the entire $400 billion program the most expensive in pentagon history.
The jet is already years behind deadline because of technical problems, and the price keeps going up.
"My department is committed to the development of the F-35. It's absolutely critical, absolutely critical that we get it right," said Secretary of Defense Leon Panetta.
Critics say the planes actually are relics designed to fight the last century's cold war instead of this century's war on terrorism, where much less expensive unmanned drones often patrol the front lines.
