Background: U.S. ASTRONAUTS USE PRESSURE SUITS AND SPECIAL HELMETS TO PROTECT THEN FROM THE HOSTILE ENVIRONMENT OF SPACE.
RECENTLY, AT SAINT LUKE'S HOSPITAL IN DENVER A SURGICAL TEAM USED SPACE-TYPE GEAR DURING A LENGTHY HIP-JOINT REPLACEMENT OPERATION. BECAUSE LARGE INCISIONS MUST REMAIN OPEN FOR SEVERAL HOURS DURING THIS TYPE OF SURGERY, THERE IS A GREATER NEED TO PROTECT THE PATIENT FROM INFECTION. DEVELOPED FOR NASA BY THE MARTIN-MARIETTA COMPANY, THE TOTAL SYSTEM INCLUDES A PORTABLE TEN-FOOT-SQUARE CLEAN ROOM SET UP INSIDE A REGULAR OPERATING ROOM. AIR FLOWS THROUGH THE SPECIALLY DESIGNED WALLS FILTERING OUT DUST AND BACTERIA.
ALL MEMBERS OF THE SURGICAL TEAM "UPWIND" OF THE PATIENT WEAR THE ASTRONAUT-TYPE HELMETS WITH VACUUM LINES ATTACHED TO REMOVE THEIR EXHALED AIR.
THE ANAESTHETIST AND OTHERS WORKING "DOWNWIND" FROM THE PATIENT WEAR THE TRADITIONAL SURGICAL MASKS.
THE ANTISEPTIC CLEAN ROOM AT SAINT LUKE'S HOSPITAL IS A GOOD EXAMPLE OF SPACE TECHNOLOGY BEING USED FOR DOWN-TO-EARTH PURPOSES.
THIS PLANE IS MAKING NUMEROUS LANDINGS IN THE INTEREST OF SAFETY. IT IS PART OF A JOINT NASA, FAA, AIR FORCE EFFORT TO IMPROVE JET LANDING SAFETY DURING BAD WEATHER.

We hope to prevent airplane skidding accidents on wet or slippery runways that are slippery from snow or ice. If we can estimate aircraft performance, and tell the pilot what the slipperiness condition is, if the runway is too slippery to operate on, for those adverse weather conditions, we can dispatch the airplane to an alternate airport, or have the airplane wait until the runway condition is safer, and let the airplane land safely. We hope to prevent airplane skidding accidents.
THE DRY LANDING STOPPING DISTANCE OF EVERY TYPE PLANE HAS TO BE CERTIFIED BY THE FAA. USING THIS KNOWN FIGURE, THE RECENTLY COMPLETED RESEARCH PROGRAM IS ATTEMPTING TO PREDICT HOW LONG IT WILL TAKE JETS TO COME TO A STOP ON WET RUNWAYS.
LANDING STUDIES HAVE BEEN MADE AT SIX AIRPORTS AROUND THE COUNTRY FROM CALIFORNIA TO NEW YORK.
USED IN THE TEST PROGRAM IS AN AUTOMOBILE EQUIPPED WITH A DIAGONAL BRAKING SYSTEM TO HELP CONTROL IT WHEN THE WHEELS ARE LOCKED AT HIGH SPEED.
ANOTHER FRICTION-MEASURING VEHICLE MEASURES SIDE FORCES.
DURING A TYPICAL TEST, THE CAR ACCELERATES TO SIXTY MILES PER HOUR...HITS THE BRAKES LOCKING A DIAGONAL PAIR OF WHEELS, AND SLIDES TO A STOP ON THE DRY PAVEMENT.
THEN THE VEHICLE THAT MEASURES SIDE FORCES TRAVELS DOWN THE RUNWAY.
FINALLY, THE 727 ITSELF LANDS AND BRAKES TO A STOP.
AS THE AIRPLANE TAKES OFF AND PREPARES TO LAND AGAIN...
...WATER TRUCKS FLOOD THE RUNWAY. THE JET NOW LANDS ON THE WET SURFACE.
NASA PROJECT MANAGER WALTER HORNE EXPLAINS HOW THE DATA IS BROUGHT TOGETHER.
Horne V/O :30
Our research shows that if we take the wet-to-dry stopping distance ratic we obtained with a car, and compare this with wet-to-dry stopping distance ratio for the aircraft when we have made these tests on a runway like this one here under wet and dry conditions, we find that these ratios are the same, or approximately the same. Therefore, wee can go out on any runway, measure the wet and dry stopping distance ratio of the car, and predict what the aircraft wet stopping distance will be, by means of hits ratio.
