US airborne laser /ABL) fails 2nd shootdown test in row

A converted Boeing Co (BA.N) 747 equipped with a powerful laser failed to shoot down a mock enemy ballistic missile, the Pentagon's Missile Defense Agency said on Thursday, the system's second botched flight test in a row.

Preliminary indications are that the so-called Airborne Laser Test Bed tracked the target's exhaust plume but did not hand off to a second, "active tracking" system as a prelude to firing the high-powered chemical laser, said Richard Lehner, an MDA spokesman.

"The transition didn't happen," he said. "Therefore, the high-energy lasing did not occur."
