Narrative:
Takeoff. Between XA30 and XB00 saturday morning. Wind 220 degrees at 7 KTS. Active runway indicated as runway 27. Ground and tower are on the same channel. Aircraft X calls for clearance to taxi. Clearance received to runway 27. Aircraft X hears a plane call in from 10 mi west and request a landing on runway 9. He is told by controller that runway 9 is acceptable and he is directed to call in at 5 mi. Aircraft X performs run-up at the end of runway 27. Pilot to the west calls in at 5 mi and is told by the controller to call in at 3 mi. A lot of talk from various pilots on the radio (about 1 min). Aircraft X is ready to go and waiting a chance to call in. Pilot to the west calls in at 3 mi and is cleared to land on runway 9. Aircraft X calls in and is cleared to takeoff on runway 27. Aircraft X taxies into place with no delay and begins takeoff roll. During takeoff roll controller calls aircraft X. Message is difficult to hear due to takeoff noise. Aircraft X lifts off and asks for a repeat of the message. Controller repeats message: turn right at earliest opportunity. Aircraft X response 'X.' controller calls again with a lot of irritation for aircraft X to turn right. Aircraft X responds that aircraft will turn right as soon as possible. Meanwhile the oncoming aircraft is clearly visible, less than 1/2 mi on final. Aircraft X flies to 200 ft above ground level, turns right, and departs to northeast. Poor judgement on the part of the controller resulted in a less than safe departure and landing for these 2 aircraft. Additionally, the anxiety and irritation on the part of the controller increased the likelihood that aircraft X would turn too early or stall while clearing the airspace. Aircraft X had few options if there had been a mechanical problem on the takeoff roll. The situation could easily have resulted in one or both pilots making an error in flight or judgement.

Title: TWR MISJUDGES TFC SPACING WHEN USING OPPOSING RWYS FOR LNDG AND DEP.
Narrative: TKOF. BTWN XA30 AND XB00 SATURDAY MORNING. WIND 220 DEGS AT 7 KTS. ACTIVE RWY INDICATED AS RWY 27. GND AND TWR ARE ON THE SAME CHANNEL. ACFT X CALLS FOR CLRNC TO TAXI. CLRNC RECEIVED TO RWY 27. ACFT X HEARS A PLANE CALL IN FROM 10 MI W AND REQUEST A LNDG ON RWY 9. HE IS TOLD BY CTLR THAT RWY 9 IS ACCEPTABLE AND HE IS DIRECTED TO CALL IN AT 5 MI. ACFT X PERFORMS RUN-UP AT THE END OF RWY 27. PLT TO THE W CALLS IN AT 5 MI AND IS TOLD BY THE CTLR TO CALL IN AT 3 MI. A LOT OF TALK FROM VARIOUS PLTS ON THE RADIO (ABOUT 1 MIN). ACFT X IS READY TO GO AND WAITING A CHANCE TO CALL IN. PLT TO THE W CALLS IN AT 3 MI AND IS CLRED TO LAND ON RWY 9. ACFT X CALLS IN AND IS CLRED TO TKOF ON RWY 27. ACFT X TAXIES INTO PLACE WITH NO DELAY AND BEGINS TKOF ROLL. DURING TKOF ROLL CTLR CALLS ACFT X. MESSAGE IS DIFFICULT TO HEAR DUE TO TKOF NOISE. ACFT X LIFTS OFF AND ASKS FOR A REPEAT OF THE MESSAGE. CTLR REPEATS MESSAGE: TURN R AT EARLIEST OPPORTUNITY. ACFT X RESPONSE 'X.' CTLR CALLS AGAIN WITH A LOT OF IRRITATION FOR ACFT X TO TURN R. ACFT X RESPONDS THAT ACFT WILL TURN R AS SOON AS POSSIBLE. MEANWHILE THE ONCOMING ACFT IS CLRLY VISIBLE, LESS THAN 1/2 MI ON FINAL. ACFT X FLIES TO 200 FT ABOVE GND LEVEL, TURNS R, AND DEPARTS TO NE. POOR JUDGEMENT ON THE PART OF THE CTLR RESULTED IN A LESS THAN SAFE DEP AND LNDG FOR THESE 2 ACFT. ADDITIONALLY, THE ANXIETY AND IRRITATION ON THE PART OF THE CTLR INCREASED THE LIKELIHOOD THAT ACFT X WOULD TURN TOO EARLY OR STALL WHILE CLRING THE AIRSPACE. ACFT X HAD FEW OPTIONS IF THERE HAD BEEN A MECHANICAL PROB ON THE TKOF ROLL. THE SIT COULD EASILY HAVE RESULTED IN ONE OR BOTH PLTS MAKING AN ERROR IN FLT OR JUDGEMENT.
