X-47B fails landing attempt again

The X-47B unmanned jet, which successfully landed twice last week on an aircraft carrier, was unable to repeat the feat Monday.
The aircraft nailed its first two landing attempts July 10 on the USS George H. W. Bush, but a third landing that day was aborted when the aircraft’s systems detected a problem with an onboard computer. Following its programming, the aircraft then flew to a “divert” field.
