Narrative:

During our ILS approach to runway 9R, we were given the clearance, 'maintain 180 to iness, contact tower.' the aircraft ahead of us was a B757, which if light, can have a reference of KTS the typical B737 reference is around KTS. This, combined with our 'iness clearance' may have resulted in compression that was not immediately detected. The aircraft ahead floated, missed both high speeds and started a slow 90 degree turnoff. We prepared for a go around. As the flare was about to begin, the B757 safely cleared the runway and we landed. Because other vantage points on the airport property may induce parallax error, it was important to document this event. Armed with this experience, timely adjustments will be made in the future to avoid compression and decisions near the flare.

Title: B737 CREW LNDG MIA AND CLOSELY FOLLOWING A B757 WERE CLOSE TO A GAR BECAUSE THE B757 MISSED 2 HIGH SPDS.

Narrative: DURING OUR ILS APCH TO RWY 9R, WE WERE GIVEN THE CLRNC, 'MAINTAIN 180 TO INESS, CONTACT TWR.' THE ACFT AHEAD OF US WAS A B757, WHICH IF LIGHT, CAN HAVE A REF OF KTS THE TYPICAL B737 REF IS AROUND KTS. THIS, COMBINED WITH OUR 'INESS CLRNC' MAY HAVE RESULTED IN COMPRESSION THAT WAS NOT IMMEDIATELY DETECTED. THE ACFT AHEAD FLOATED, MISSED BOTH HIGH SPDS AND STARTED A SLOW 90 DEG TURNOFF. WE PREPARED FOR A GAR. AS THE FLARE WAS ABOUT TO BEGIN, THE B757 SAFELY CLRED THE RWY AND WE LANDED. BECAUSE OTHER VANTAGE POINTS ON THE ARPT PROPERTY MAY INDUCE PARALLAX ERROR, IT WAS IMPORTANT TO DOCUMENT THIS EVENT. ARMED WITH THIS EXPERIENCE, TIMELY ADJUSTMENTS WILL BE MADE IN THE FUTURE TO AVOID COMPRESSION AND DECISIONS NEAR THE FLARE.
