Narrative:

ILS runway 4R bos, ATIS reporting 7 scattered and good visibility. IOE first officer flying, captain check airman in command. Normal approach, but surprisingly did not see runway until decision ht (200 ft AGL) in poor visibility/mist. First officer made landing with some verbal and manual assistance from captain. At touchdown, heard 'go around if able.' with speed brakes and reversers deployed, near maximum gross weight landing, and unaware of problem, I said 'unable,' and aggressively stopped aircraft, only then seeing B727 crossing from 11 - 1 O'clock position on runway 15R, apparently under heavy braking. Upon inquiry to tower, was asked to call on telephone, as was the other captain. Tower supervisor, apologized and stated that investigation of controller's error was under way, and we exchanged information. He said when we 'popped out' at 200 ft, the tower controller realized the conflict and ordered me to go around. (My so informed me afterward that he did hear a go around order 'in the flare,' but I did not possibly due to the verbal and manual assistance being given to the IOE first officer.) at some point, she apparently ordered the other B727 to abort takeoff at high speed, on a different frequency. I stopped prior to the intersection, he did not. Visibility was poor, but estimated separation was 500-1000 ft. I believe in retrospect that if I had heard the original go around order and complied, considering weight, performance, and timing, the total separation would have been even less, although some of it vertical. If the other B727 had continued takeoff, and we did go around, a very near miss was likely at best. All this in retrospect, of course.

Title: B727 CREW LNDG AT BOS AVOIDS POSSIBLE COLLISION AT INTERSECTING RWYS.

Narrative: ILS RWY 4R BOS, ATIS RPTING 7 SCATTERED AND GOOD VISIBILITY. IOE FO FLYING, CAPT CHK AIRMAN IN COMMAND. NORMAL APCH, BUT SURPRISINGLY DID NOT SEE RWY UNTIL DECISION HT (200 FT AGL) IN POOR VISIBILITY/MIST. FO MADE LNDG WITH SOME VERBAL AND MANUAL ASSISTANCE FROM CAPT. AT TOUCHDOWN, HEARD 'GO AROUND IF ABLE.' WITH SPD BRAKES AND REVERSERS DEPLOYED, NEAR MAX GROSS WT LNDG, AND UNAWARE OF PROB, I SAID 'UNABLE,' AND AGGRESSIVELY STOPPED ACFT, ONLY THEN SEEING B727 XING FROM 11 - 1 O'CLOCK POS ON RWY 15R, APPARENTLY UNDER HVY BRAKING. UPON INQUIRY TO TWR, WAS ASKED TO CALL ON TELEPHONE, AS WAS THE OTHER CAPT. TWR SUPVR, APOLOGIZED AND STATED THAT INVESTIGATION OF CTLR'S ERROR WAS UNDER WAY, AND WE EXCHANGED INFO. HE SAID WHEN WE 'POPPED OUT' AT 200 FT, THE TWR CTLR REALIZED THE CONFLICT AND ORDERED ME TO GO AROUND. (MY SO INFORMED ME AFTERWARD THAT HE DID HEAR A GAR ORDER 'IN THE FLARE,' BUT I DID NOT POSSIBLY DUE TO THE VERBAL AND MANUAL ASSISTANCE BEING GIVEN TO THE IOE FO.) AT SOME POINT, SHE APPARENTLY ORDERED THE OTHER B727 TO ABORT TKOF AT HIGH SPD, ON A DIFFERENT FREQ. I STOPPED PRIOR TO THE INTXN, HE DID NOT. VISIBILITY WAS POOR, BUT ESTIMATED SEPARATION WAS 500-1000 FT. I BELIEVE IN RETROSPECT THAT IF I HAD HEARD THE ORIGINAL GAR ORDER AND COMPLIED, CONSIDERING WT, PERFORMANCE, AND TIMING, THE TOTAL SEPARATION WOULD HAVE BEEN EVEN LESS, ALTHOUGH SOME OF IT VERT. IF THE OTHER B727 HAD CONTINUED TKOF, AND WE DID GAR, A VERY NEAR MISS WAS LIKELY AT BEST. ALL THIS IN RETROSPECT, OF COURSE.
