Narrative:

Monitoring both unicom 122.8 and clearance 125.65. On taxi out; we received our clearance and completed the taxi and pre takeoff checklists. The first officer was running the checklists and copying and reading back the clearance. I was monitoring and responding to checklist items and clearance. Because the first officer was very busy I also was monitoring unicom for other aircraft in the area. We chose to use runway 3 after reviewing the ASOS WX: clear skies; wind 070 degrees at 8 KTS; and not seeing or hearing any other traffic in the area. At the end of the runway we informed clearance that we were ready for release; he came back with the release with a very close void time and after takeoff instructions; we started the takeoff roll in a hurry-up mindset because of the void time and I inadvertently missed the takeoff call on unicom. I had been monitoring unicom and had not heard any other traffic. Clearance; who was also departure control; informed us that no other traffic was observed in the area. At midfield and approximately V1; I observed a small cessna; apparently on takeoff climb out directly ahead and appeared to be about 400 ft above the runway. I rotated slowly and made a slight left turn to increase the distance between us; continued straight out to make sure that the right turn I would be making as part of the departure would not interfere with his pattern; since it appeared that he had not seen us. My estimation of the distances involved were 500 ft horizontal behind him and 400 ft below. This was a wake-up call to not let anything hurry me up and change my procedures.

Title: CITATION CE550 FLT CREW ENCOUNTERS ANOTHER ACFT DURING TKOF AT MRH.

Narrative: MONITORING BOTH UNICOM 122.8 AND CLRNC 125.65. ON TAXI OUT; WE RECEIVED OUR CLRNC AND COMPLETED THE TAXI AND PRE TKOF CHKLISTS. THE FO WAS RUNNING THE CHKLISTS AND COPYING AND READING BACK THE CLRNC. I WAS MONITORING AND RESPONDING TO CHKLIST ITEMS AND CLRNC. BECAUSE THE FO WAS VERY BUSY I ALSO WAS MONITORING UNICOM FOR OTHER ACFT IN THE AREA. WE CHOSE TO USE RWY 3 AFTER REVIEWING THE ASOS WX: CLR SKIES; WIND 070 DEGS AT 8 KTS; AND NOT SEEING OR HEARING ANY OTHER TFC IN THE AREA. AT THE END OF THE RWY WE INFORMED CLRNC THAT WE WERE READY FOR RELEASE; HE CAME BACK WITH THE RELEASE WITH A VERY CLOSE VOID TIME AND AFTER TKOF INSTRUCTIONS; WE STARTED THE TKOF ROLL IN A HURRY-UP MINDSET BECAUSE OF THE VOID TIME AND I INADVERTENTLY MISSED THE TKOF CALL ON UNICOM. I HAD BEEN MONITORING UNICOM AND HAD NOT HEARD ANY OTHER TFC. CLRNC; WHO WAS ALSO DEP CTL; INFORMED US THAT NO OTHER TFC WAS OBSERVED IN THE AREA. AT MIDFIELD AND APPROX V1; I OBSERVED A SMALL CESSNA; APPARENTLY ON TKOF CLBOUT DIRECTLY AHEAD AND APPEARED TO BE ABOUT 400 FT ABOVE THE RWY. I ROTATED SLOWLY AND MADE A SLIGHT L TURN TO INCREASE THE DISTANCE BTWN US; CONTINUED STRAIGHT OUT TO MAKE SURE THAT THE R TURN I WOULD BE MAKING AS PART OF THE DEP WOULD NOT INTERFERE WITH HIS PATTERN; SINCE IT APPEARED THAT HE HAD NOT SEEN US. MY ESTIMATION OF THE DISTANCES INVOLVED WERE 500 FT HORIZ BEHIND HIM AND 400 FT BELOW. THIS WAS A WAKE-UP CALL TO NOT LET ANYTHING HURRY ME UP AND CHANGE MY PROCS.
