Narrative:

Normal, stabilized approach to runway 30R in good VFR, daylight conditions. Very light chop, wind 250 degrees at 16-20 KTS. Developed high sink rate over threshold. Added considerable power but was unable to arrest sink rate. Aircraft touched down firm, bounced, and touched down normally. 2 flight attendants seated on aft jump seats reported back and neck pains and were taken to local clinic. Subsequent postflt revealed that 4 oxygen masks had come down and no other abnormalities. Runway 30R approach is over a riverbed and is known to produce sinks about 1/3 of a mi out. There was a slight sink at that position, but then the approach was stabilized until the threshold.

Title: A B727 FLC IS INVOLVED IN A HARD LNDG THAT CAUSED BACK AND NECK PAINS TO THE 2 FLT ATTENDANTS SEATED IN THE REAR JUMP SEATS AT MSP, MN.

Narrative: NORMAL, STABILIZED APCH TO RWY 30R IN GOOD VFR, DAYLIGHT CONDITIONS. VERY LIGHT CHOP, WIND 250 DEGS AT 16-20 KTS. DEVELOPED HIGH SINK RATE OVER THRESHOLD. ADDED CONSIDERABLE PWR BUT WAS UNABLE TO ARREST SINK RATE. ACFT TOUCHED DOWN FIRM, BOUNCED, AND TOUCHED DOWN NORMALLY. 2 FLT ATTENDANTS SEATED ON AFT JUMP SEATS RPTED BACK AND NECK PAINS AND WERE TAKEN TO LCL CLINIC. SUBSEQUENT POSTFLT REVEALED THAT 4 OXYGEN MASKS HAD COME DOWN AND NO OTHER ABNORMALITIES. RWY 30R APCH IS OVER A RIVERBED AND IS KNOWN TO PRODUCE SINKS ABOUT 1/3 OF A MI OUT. THERE WAS A SLIGHT SINK AT THAT POS, BUT THEN THE APCH WAS STABILIZED UNTIL THE THRESHOLD.
