Narrative:

Training in progress. Air carrier X in position for takeoff. Previous arrival was slow to exit runway, traffic was cga Y, an light transport, on short final. Cga Y was cleared to land; air carrier X was cleared for takeoff after the traffic cleared runway. Cga Y touched down just prior to air carrier X rotating, approximately 3000'-4000' apart. As local controller (training instrument) I was trying to let trnee handle it on his own to build his confidence (as I prodded). Traffic on runway did not respond and exit quickly enough. Air carrier X had already been held unnecessarily, and I let the operation continue, not realizing it was going to be this close.

Title: LTT LANDED WHILE A DEP ACR WAS JUST LIFTING OFF.

Narrative: TRNING IN PROGRESS. ACR X IN POS FOR TKOF. PREVIOUS ARR WAS SLOW TO EXIT RWY, TFC WAS CGA Y, AN LTT, ON SHORT FINAL. CGA Y WAS CLRED TO LAND; ACR X WAS CLRED FOR TKOF AFTER THE TFC CLRED RWY. CGA Y TOUCHED DOWN JUST PRIOR TO ACR X ROTATING, APPROX 3000'-4000' APART. AS LCL CTLR (TRNING INSTR) I WAS TRYING TO LET TRNEE HANDLE IT ON HIS OWN TO BUILD HIS CONFIDENCE (AS I PRODDED). TFC ON RWY DID NOT RESPOND AND EXIT QUICKLY ENOUGH. ACR X HAD ALREADY BEEN HELD UNNECESSARILY, AND I LET THE OPERATION CONTINUE, NOT REALIZING IT WAS GOING TO BE THIS CLOSE.
