The missile failed to lock onto the helicopter and exploded on the ground.

At least one report said that the missile had failed.

First test occurred in 2006, when the missile failed 40 seconds after launch.

The missile left a 16-foot crater in a field but failed to detonate.

He never knew that his missile failed to guide.

It was the second time the missile had failed in three test launchings.

We understand why the missile failed and know how to correct it.

According to preliminary reports, the missile failed in mid-flight 35-40 seconds after launch.

Late that year, two missiles failed tests and the project was delayed for three months before completing development in April 2003.

However, after a successful boost the missile failed to transition to the sustain phase of flight.
