It looks like the reversers were the primary method of stopping for all of the aircraft that night. I was the first flight into Reno one morning and realized after coming out of reverse if I didn't go back into reverse on a 737 I would be off the end. I was empty. If they couldn't get the reversers out for 18 seconds, they had little chance of stopping. Midway had shut the airport down due to poor breaking action and plowed the runway prior to this crash and got a satisfactory braking action from a truck but reports were there were hundreds of feet of glare ice at the end of 31C.
FAA has pulled FDR info out of previous arrivals checking their deceleration rate on landing.
Something to think about considering a close to V1 abort on ice with one engine out.
