Narrative:

After trying to contact ground control, I changed to tower frequency and began broadcasting in the blind my intentions to taxi and take off. Upon completion of our checklists and clearing the area, we departed. As we approached V1, I caught a reflection in the tower glass. At second glance, it was a light gun signal flashing red. By this time, we were passing V1 and it was too late to stop. Once airborne, I contacted center for my IFR clearance, then was told to contact tower again. After calling hailey tower again, the controller responded pretty upset and requested my name, number, home base, etc. I gave him my name and phone number, then was told he had me for: failure to use a radio, taxiway incursion, runway incursion, and departing with men and equipment on the runway. XA00 on a friday night, we never saw any men and equipment. As for the rest, I believe there are 2 main errors: 1) tower's failure to respond, and 2) my belief that the tower was closed. Supplemental information from acn 546166: captain called ground control on 121.7 2 times and tried to get a clearance to taxi. He told me to taxi to runway 13. We started rolling. By the time the captain saw the red light gun we had rotated and were starting our climb out. I believe this whole event would not have happened if we (the captain and I) (first officer) would have looked at the hours of operation.

UPON COMPLETION OF OUR CHKLISTS AND CLRING THE AREA, WE DEPARTED. AS WE APCHED V1, I CAUGHT A REFLECTION IN THE TWR GLASS. AT SECOND GLANCE, IT WAS A LIGHT GUN SIGNAL FLASHING RED.
