Narrative:
I received an IFR clearance with a 5 min window. Heavy dew had fallen the night before. From experience, I knew that the engine runup would clear it off the window, so I didn't do it by hand to save time. This worked, but as the water cleared, all the numerous bug splats from the previous trip were revealed. This was only a minor reduction in visibility, but was a contributing distraction. I was worrying whether to stop, clean the window, and pick up a new clearance or not. Aircraft Y had a bad transmitter. Its xmissions were faint, staticky and garbled. I didn't realize he existed at first. A third aircraft, aircraft Z, was landing. I transmit, 'nxxxx taking the active runway 25 at central jersey.' aircraft Y calls. I hear '...central jersey...seven....' I transmit 'what was that?' aircraft Z calls 'nxxxx base to final runway 7 central jersey.' as I'm past the hold short line, I taxi across and off, and transmit 'nxxxx crossing the active, I'll taxi off the other side and clear the runway.' aircraft Z lands and attempts to exit the runway onto the taxiway I am sitting on. I'm now turned around, facing the runway again. Aircraft Z taxies carefully around me, going onto the grass, and heads for a parking space. I call 'nxxxx departing runway 25 central jersey' and again taxi onto the runway. Full power, check engine RPM and oil pressure. About 1/3 of the way down the runway, at about 50 mph, I notice an aircraft finishing a turn to exit the runway (aircraft Y). Aircraft Y had obviously entered the runway about the same time I did, from the opposite end. As an abort might cause a collision, and aircraft Y wasn't on a takeoff roll, I elected to fly. Passed aircraft Y about 100 ft over aircraft Y, just as its tail was leaving the runway. Heard from aircraft Y, '...clear of the active....' told aircraft Y that his transmitter was garbled and almost unreadable.

Title: PLT IN C172, ACFT X, AT 47N ARPT ON CTAF AFTER STARTING TKOF ROLL OBSERVES ACFT Y ON OPPOSITE END OF RWY EXITING. PLT IN ACFT X ELECTS TO CONTINUE TKOF AND PASSES OVER EXITING ACFT Y BY 100 FT.
Narrative: I RECEIVED AN IFR CLRNC WITH A 5 MIN WINDOW. HVY DEW HAD FALLEN THE NIGHT BEFORE. FROM EXPERIENCE, I KNEW THAT THE ENG RUNUP WOULD CLR IT OFF THE WINDOW, SO I DIDN'T DO IT BY HAND TO SAVE TIME. THIS WORKED, BUT AS THE WATER CLRED, ALL THE NUMEROUS BUG SPLATS FROM THE PREVIOUS TRIP WERE REVEALED. THIS WAS ONLY A MINOR REDUCTION IN VISIBILITY, BUT WAS A CONTRIBUTING DISTR. I WAS WORRYING WHETHER TO STOP, CLEAN THE WINDOW, AND PICK UP A NEW CLRNC OR NOT. ACFT Y HAD A BAD XMITTER. ITS XMISSIONS WERE FAINT, STATICKY AND GARBLED. I DIDN'T REALIZE HE EXISTED AT FIRST. A THIRD ACFT, ACFT Z, WAS LNDG. I XMIT, 'NXXXX TAKING THE ACTIVE RWY 25 AT CENTRAL JERSEY.' ACFT Y CALLS. I HEAR '...CENTRAL JERSEY...SEVEN....' I XMIT 'WHAT WAS THAT?' ACFT Z CALLS 'NXXXX BASE TO FINAL RWY 7 CENTRAL JERSEY.' AS I'M PAST THE HOLD SHORT LINE, I TAXI ACROSS AND OFF, AND XMIT 'NXXXX XING THE ACTIVE, I'LL TAXI OFF THE OTHER SIDE AND CLR THE RWY.' ACFT Z LANDS AND ATTEMPTS TO EXIT THE RWY ONTO THE TXWY I AM SITTING ON. I'M NOW TURNED AROUND, FACING THE RWY AGAIN. ACFT Z TAXIES CAREFULLY AROUND ME, GOING ONTO THE GRASS, AND HEADS FOR A PARKING SPACE. I CALL 'NXXXX DEPARTING RWY 25 CENTRAL JERSEY' AND AGAIN TAXI ONTO THE RWY. FULL PWR, CHK ENG RPM AND OIL PRESSURE. ABOUT 1/3 OF THE WAY DOWN THE RWY, AT ABOUT 50 MPH, I NOTICE AN ACFT FINISHING A TURN TO EXIT THE RWY (ACFT Y). ACFT Y HAD OBVIOUSLY ENTERED THE RWY ABOUT THE SAME TIME I DID, FROM THE OPPOSITE END. AS AN ABORT MIGHT CAUSE A COLLISION, AND ACFT Y WASN'T ON A TKOF ROLL, I ELECTED TO FLY. PASSED ACFT Y ABOUT 100 FT OVER ACFT Y, JUST AS ITS TAIL WAS LEAVING THE RWY. HEARD FROM ACFT Y, '...CLR OF THE ACTIVE....' TOLD ACFT Y THAT HIS XMITTER WAS GARBLED AND ALMOST UNREADABLE.
