Narrative:

At the time of the incident, a thunderstorm was approaching the airport from the east and visibility was rapidly decreasing. The final controller was very busy with numerous VFR aircraft attempting to beat the WX and return to the airport in VFR conditions. Needless to say, the local controller was very busy when during this time it came to pass that 2 smas ended up landing on one runway approximately 500-700 ft apart. It was felt by the supervisor based upon the severe WX approaching, it was safer to allow the second aircraft to land rather than send him around into a thunderstorm.

Original NASA ASRS Text

Title: LTSS BTWN 2 SMA ACFT LNDG ON SAME RWY. OPERATIONAL ERROR.

Narrative: AT THE TIME OF THE INCIDENT, A TSTM WAS APCHING THE ARPT FROM THE E AND VISIBILITY WAS RAPIDLY DECREASING. THE FINAL CTLR WAS VERY BUSY WITH NUMEROUS VFR ACFT ATTEMPTING TO BEAT THE WX AND RETURN TO THE ARPT IN VFR CONDITIONS. NEEDLESS TO SAY, THE LCL CTLR WAS VERY BUSY WHEN DURING THIS TIME IT CAME TO PASS THAT 2 SMAS ENDED UP LNDG ON ONE RWY APPROX 500-700 FT APART. IT WAS FELT BY THE SUPVR BASED UPON THE SEVERE WX APCHING, IT WAS SAFER TO ALLOW THE SECOND ACFT TO LAND RATHER THAN SEND HIM AROUND INTO A TSTM.
