Joint Strike Fighter Competition
For the Joint Strike Fighter program two prototypes were built - Boeing's X-32 and Lockheeds X-35. On 18th September 2000 the X-32 had it´s first flight and on 24th October the X-35. Both had to demonstrate the capability of vertical takeoff and landing. On 26th October 2001 the X-35 was declared as the winner, because of the conventional design which would lower the production cost and the X-32 had problems because it was too heavy for it´s size. And because the X-35 was more agile.
