Narrative

I WAS WITH ONE OF MY STUDENTS ON AN INST XCOUNTRY. WE WERE DEPARTING GALLUP; NM. THE RWY ALIGNMENT IS 6/24. WIND WAS LESS THAN 5 KTS. RWY 24 IS CLOSER TO THE TERMINAL; BUT THERE WERE 2 AIRPLANES ARRIVING RWY 6 AND WE DECIDED TO USE RWY 6. THE SECOND AIRPLANE LANDED; AND AS HE WAS TAXIING TO THE RAMP; HE WAS CARRYING ON A CONVERSATION ON CTAF WITH ANOTHER PLT. ONCE THEY GOT OFF THE RADIO; MY STUDENT CALLED DEPARTING RWY 6. WE TAXIED INTO POS AND STARTED OUR TKOF ROLL. MY STUDENT JUST CALLED OUT 60 KTS WHEN I SAW MOVEMENT AT THE FAR END OF THE RWY. I IMMEDIATELY TOOK THE CTLS; REDUCED THROTTLE AND STOPPED THE AIRPLANE; HDG TO THE L SIDE OF THE RWY. THE OTHER PLT CONTINUED HIS TKOF ROLL AND ROTATED LESS THAN 500 FT IN FRONT OF US. THE OTHER PLT DIDN'T SEEM TOO CONCERNED ABOUT THE INCIDENT. WE NEVER HEARD THE OTHER PLT MAKE A CALL ON THE RADIO. 1 OF 2 THINGS HAPPENED. EITHER WE UNKNOWINGLY STEPPED ON EACH OTHER; WHICH SEEMS UNLIKELY BECAUSE ONE OF US SHOULD HAVE HAD A LONGER XMISSION AND AS A RESULT SHOULD HAVE BEEN HEARD BY THE OTHER. THE OTHER SIT IS THAT THE OTHER PLT DID NOT MAKE A RADIO CALL.
