Narrative:

We visually idented a thunderstorm over the VOR which is approximately 3 mi south of the runway. The runway was dry. We checked the performance manual for climb limited weight landing runway 19. The limit was 194000 pounds at runway 28C which was our exact weight. Between 23 DME and approximately 3 mi final, tower called the wind as 180 degrees at 5 KTS, then calm, then north at 5 KTS with the last report being calm. We elected to continue the visual for runway 19. Just prior to crossing the threshold of the runway, we experienced a windshear which caused a fairly rapid sinker which resulted in a firm touchdown although not unusually hard. At the gate we were informed by a flight attendant we had dropped oxygen masks at rows 9 and 16. During the first officer preflight for the return leg to mia, he noticed a scuff of the sidewall of the 8 main gear and 3 small holes in the bottom of the fuselage aft of the wing. One of the holes was in front of the VHF antenna and 2 aft with the largest one being approximately 2 inches by 4 inches in size.

Title: B757 FLC ENCOUNTERS WINDSHEAR LNDG AT TGU.

Narrative: WE VISUALLY IDENTED A TSTM OVER THE VOR WHICH IS APPROX 3 MI S OF THE RWY. THE RWY WAS DRY. WE CHKED THE PERFORMANCE MANUAL FOR CLB LIMITED WT LNDG RWY 19. THE LIMIT WAS 194000 LBS AT RWY 28C WHICH WAS OUR EXACT WT. BTWN 23 DME AND APPROX 3 MI FINAL, TWR CALLED THE WIND AS 180 DEGS AT 5 KTS, THEN CALM, THEN N AT 5 KTS WITH THE LAST RPT BEING CALM. WE ELECTED TO CONTINUE THE VISUAL FOR RWY 19. JUST PRIOR TO XING THE THRESHOLD OF THE RWY, WE EXPERIENCED A WINDSHEAR WHICH CAUSED A FAIRLY RAPID SINKER WHICH RESULTED IN A FIRM TOUCHDOWN ALTHOUGH NOT UNUSUALLY HARD. AT THE GATE WE WERE INFORMED BY A FLT ATTENDANT WE HAD DROPPED OXYGEN MASKS AT ROWS 9 AND 16. DURING THE FO PREFLT FOR THE RETURN LEG TO MIA, HE NOTICED A SCUFF OF THE SIDEWALL OF THE 8 MAIN GEAR AND 3 SMALL HOLES IN THE BOTTOM OF THE FUSELAGE AFT OF THE WING. ONE OF THE HOLES WAS IN FRONT OF THE VHF ANTENNA AND 2 AFT WITH THE LARGEST ONE BEING APPROX 2 INCHES BY 4 INCHES IN SIZE.
