Narrative:

We were vectored for the ILS runway 19L in sfo. WX was around 3000 ft and visibility better than 5 miles. We were cleared for the ILS (approach); followed by clearance to land. There was a heavy aircraft about 5 miles ahead which landed safely. Shortly after we were cleared to land; we heard another company aircraft was cleared for takeoff from runway 10. We were asked to slow to approach speed. However; we were already there. We could not believe it. I saw it and after I (first officer/pm) made my 300 ft callout; we were sent around. Last time I saw company aircraft it was rotating and with relative movement across our windscreen. Next time it was on our 10:30 position and climbing. Based on runway length and initiation of GA; I am estimating we were within 2000 to 1500 ft of each other. We even felt the wake as we were climbing. The purpose of this report is to find out if this was an honest mistake or a recurrent situation. After vectors around the pattern we landed safely at sfo.

Title: B737 ON APCH TO RWY 19L AT SFO MUST GAR TO AVOID CONFLICT WITH DEP OFF ONE OF THE RWY 10'S.

Narrative: WE WERE VECTORED FOR THE ILS RWY 19L IN SFO. WX WAS AROUND 3000 FT AND VISIBILITY BETTER THAN 5 MILES. WE WERE CLRED FOR THE ILS (APCH); FOLLOWED BY CLRNC TO LAND. THERE WAS A HEAVY ACFT ABOUT 5 MILES AHEAD WHICH LANDED SAFELY. SHORTLY AFTER WE WERE CLRED TO LAND; WE HEARD ANOTHER COMPANY ACFT WAS CLRED FOR TAKEOFF FROM RWY 10. WE WERE ASKED TO SLOW TO APCH SPEED. HOWEVER; WE WERE ALREADY THERE. WE COULD NOT BELIEVE IT. I SAW IT AND AFTER I (FO/PM) MADE MY 300 FT CALLOUT; WE WERE SENT AROUND. LAST TIME I SAW COMPANY ACFT IT WAS ROTATING AND WITH RELATIVE MOVEMENT ACROSS OUR WINDSCREEN. NEXT TIME IT WAS ON OUR 10:30 POSITION AND CLIMBING. BASED ON RWY LENGTH AND INITIATION OF GA; I AM ESTIMATING WE WERE WITHIN 2000 TO 1500 FT OF EACH OTHER. WE EVEN FELT THE WAKE AS WE WERE CLBING. THE PURPOSE OF THIS RPT IS TO FIND OUT IF THIS WAS AN HONEST MISTAKE OR A RECURRENT SITUATION. AFTER VECTORS AROUND THE PATTERN WE LANDED SAFELY AT SFO.
