WASHINGTON (AP) - Just before an American Airlines plane ran off a Wyoming runway last December, pilots struggled to engage the brakes and thrust reversers that help slow speed.
    
The government released the transcript of a cockpit voice recorder Friday and it shows the first officer of the Boeing 757 saying in a strained voice "no reverse ... I can't get it."
    
The captain calls for the brakes to be used, but the first officer says he doesn't know what's wrong and then says, "We're screwed."
    
Seconds later the plane with 181 people aboard can be heard rumbling off the runway in Jackson Hole. No one was injured in the incident.
    
Safety experts say runway overruns are the most dangerous type of airline accident worldwide.
