DURING THE DESCENT TO THE OUTER MARKER FOR A VISUAL APPROACH WITH AN ILS BACKUP TO RUNWAY 26R, THE PILOT IN COMMAND DID NOT DESCEND TO A POINT WHERE A STABILIZED APPROACH TO LANDING COULD BE COMPLETED. THE AIRPLANE REPORTEDLY CROSSED THE OUTER MARKER WITH A FULL SCALE FLY DOWN DEFLECTION ON THE ILS GLIDE SLOPE INDICATOR. THE PILOT REPORTED THAT HE ATTAINED THE GLIDE SLOPE FROM ABOVE WHEN HE WAS ABOUT ONE MILE FROM THE THRESHOLD. THE AIRPLANE WAS FLARED FOR LANDING AT AN EXCESSIVE ALTITUDE AND TOUCHDOWN WAS NOT MADE UNTIL AT LEAST 1,500 FEET DOWN THE RUNWAY. THE AIRPLANE TOUCHED DOWN HARD, BOUNCED AND ON THE SECOND TOUCHDOWN MADE RUNWAY CONTACT WITH ALL THREE GEARS OR POSSIBLY SLIGHTLY NOSE GEAR FIRST.
