Narrative:
Air carrier X cleared to land on runway 34 following flight of 2 fgt's Y. He had reported in sight. Fgt's Y landed and what turned out to be the lead aircraft was clearing the runway (9999') when air carrier X was cleared to land. Second element was behind crash fire rescue equipment building and not visible to tower. This resulted in air carrier X on runway with second fgt just turning off, but not clear. Air carrier X made midfield taxiway anyway, and there was plenty of runway between them since second fgt Y was almost off. I did not notice the 2 fgt's Y had not stayed together on the runway until the second one passed into view after being blocked from sight by the crash fire rescue equipment building. The air carrier X was at a critical phase, and a go around would have been less safe. They had almost 10000' of runway between them.
Original NASA ASRS Text
Title: ACR X HAD LESS THAN STANDARD SEPARATION FROM FGT'S Y. SYSTEM ERROR. ACR X LANDED ON OCCUPIED RWY. PLTDEV.
Narrative: ACR X CLRED TO LAND ON RWY 34 FOLLOWING FLT OF 2 FGT'S Y. HE HAD RPTED IN SIGHT. FGT'S Y LANDED AND WHAT TURNED OUT TO BE THE LEAD ACFT WAS CLRING THE RWY (9999') WHEN ACR X WAS CLRED TO LAND. SECOND ELEMENT WAS BEHIND CFR BUILDING AND NOT VISIBLE TO TWR. THIS RESULTED IN ACR X ON RWY WITH SECOND FGT JUST TURNING OFF, BUT NOT CLR. ACR X MADE MIDFIELD TXWY ANYWAY, AND THERE WAS PLENTY OF RWY BTWN THEM SINCE SECOND FGT Y WAS ALMOST OFF. I DID NOT NOTICE THE 2 FGT'S Y HAD NOT STAYED TOGETHER ON THE RWY UNTIL THE SECOND ONE PASSED INTO VIEW AFTER BEING BLOCKED FROM SIGHT BY THE CFR BUILDING. THE ACR X WAS AT A CRITICAL PHASE, AND A GO AROUND WOULD HAVE BEEN LESS SAFE. THEY HAD ALMOST 10000' OF RWY BTWN THEM.
