Narrative:

We flew to opf on a position flight and landed on runway 9L at approximately XA30L. The tower closed and we departed runway 9L again at approximately XC00L. After departure we were informed (by another departing aircraft; I think) that the runway is closed after XB00L. I had the first officer complete flight planning because he was due a PIC 135.299 check the following day. We both reviewed the NOTAMS on our flight plan package and there was no NOTAM for the runway closure. I reviewed the airport information tab on flight planning web site and found it under the remarks section. In retrospect; I should have taken a look at all NOTAMS and thoroughly reviewed all the airport information for opf; not the ones that were printed on our flight plan package. Since we had just landed on the same runway just over 1 hour prior I would never have guessed that it was NOTAM'd closed. In the future I will definitely review all airport information.

Title: FLT CREW DEPARTS RWY 9L AT OPF AFTER TOWER AND RWY CLOSE.

Narrative: WE FLEW TO OPF ON A POSITION FLT AND LANDED ON RWY 9L AT APPROX XA30L. THE TOWER CLOSED AND WE DEPARTED RWY 9L AGAIN AT APPROX XC00L. AFTER DEP WE WERE INFORMED (BY ANOTHER DEPARTING ACFT; I THINK) THAT THE RWY IS CLOSED AFTER XB00L. I HAD THE FO COMPLETE FLT PLANNING BECAUSE HE WAS DUE A PIC 135.299 CHECK THE FOLLOWING DAY. WE BOTH REVIEWED THE NOTAMS ON OUR FLT PLAN PACKAGE AND THERE WAS NO NOTAM FOR THE RWY CLOSURE. I REVIEWED THE ARPT INFORMATION TAB ON FLT PLANNING WEB SITE AND FOUND IT UNDER THE REMARKS SECTION. IN RETROSPECT; I SHOULD HAVE TAKEN A LOOK AT ALL NOTAMS AND THOROUGHLY REVIEWED ALL THE ARPT INFORMATION FOR OPF; NOT THE ONES THAT WERE PRINTED ON OUR FLT PLAN PACKAGE. SINCE WE HAD JUST LANDED ON THE SAME RWY JUST OVER 1 HOUR PRIOR I WOULD NEVER HAVE GUESSED THAT IT WAS NOTAM'D CLOSED. IN THE FUTURE I WILL DEFINITELY REVIEW ALL ARPT INFORMATION.
