Narrative:

Small aircraft landed runway 8. (Just about closing, no traffic.) I asked small aircraft his destination on airport, on his rollout, he advised he wished to depart for ft meade. I advised him runway 26 was available, wind was light and variable. He said that would be fine. I issued a back taxi on the runway for full length departure. I was working on traffic count and closing logs waiting for him to advise he was ready, when I saw him rolling and rotate. No clearance was issued. Field check was in progress, but vehicle was not on or crossing runway 8/26. Cause: I didn't issue position and hold, but I also didn't issue takeoff clearance, only 'runway 26 is available for departure' and 'back taxi on runway for full length.' correction: students need more interaction training at controled fields, especially when they are based at an uncontrolled field. This wouldn't be a bad idea on biennials. Our uncontrolled field pilots do not know: hold lines, read back hold short instructions, what an ATIS is or what it's for. Airspace, VFR (actual minimums), scud runners.

Title: SMA MADE AN UNAUTH TKOF. NIGHT OP.

Narrative: SMA LANDED RWY 8. (JUST ABOUT CLOSING, NO TFC.) I ASKED SMA HIS DEST ON ARPT, ON HIS ROLLOUT, HE ADVISED HE WISHED TO DEPART FOR FT MEADE. I ADVISED HIM RWY 26 WAS AVAILABLE, WIND WAS LIGHT AND VARIABLE. HE SAID THAT WOULD BE FINE. I ISSUED A BACK TAXI ON THE RWY FOR FULL LENGTH DEP. I WAS WORKING ON TFC COUNT AND CLOSING LOGS WAITING FOR HIM TO ADVISE HE WAS READY, WHEN I SAW HIM ROLLING AND ROTATE. NO CLRNC WAS ISSUED. FIELD CHK WAS IN PROGRESS, BUT VEHICLE WAS NOT ON OR XING RWY 8/26. CAUSE: I DIDN'T ISSUE POS AND HOLD, BUT I ALSO DIDN'T ISSUE TKOF CLRNC, ONLY 'RWY 26 IS AVAILABLE FOR DEP' AND 'BACK TAXI ON RWY FOR FULL LENGTH.' CORRECTION: STUDENTS NEED MORE INTERACTION TRAINING AT CTLED FIELDS, ESPECIALLY WHEN THEY ARE BASED AT AN UNCTLED FIELD. THIS WOULDN'T BE A BAD IDEA ON BIENNIALS. OUR UNCTLED FIELD PLTS DO NOT KNOW: HOLD LINES, READ BACK HOLD SHORT INSTRUCTIONS, WHAT AN ATIS IS OR WHAT IT'S FOR. AIRSPACE, VFR (ACTUAL MINIMUMS), SCUD RUNNERS.
