Narrative:

I filed for an eastbound flight to dpk. After 1/2 hour, controller came back and said that direction was unavailable. In the first contact he asked if I was using runway 27. 45 mins later, clearance was to the west to allentown, wind was approximately 10 KTS from the east. He gave me departure release clearance, void in 2 mins. I called ready runway 27 and took off on runway 9 into the approach corridor for newark where the miss occurred. (Correct for wind, but not for clearance.) I was confused by the wind direction and the controller's question and direction of use runway 27. Also time between clearance (sitting midfield) and quick release did not help. Saw other plane on climb out and turned to the west. I believe I was fixated on takeoff without a tailwind of 10 KTS for safety and short runway!
