Narrative:

Tower issued the clearance 'line up and wait runway 5' hawker jet traffic landing 32.' the captain called for the takeoff checklist which we completed as we were rolling into position. After lining up on the runway the thrust levers were advanced and we began our takeoff roll. Very shortly after we began rolling and just as I saw the runway 32 landing traffic ATC called and said; 'cancel takeoff clearance.' I knew immediately we had messed up because I remember ATC telling us there was landing traffic runway 32 after his line up and wait command. We immediately aborted the takeoff; kept the aircraft below 80 KTS and came to a stop on runway 5. We then taxied off the runway; made appropriate announcements; contacted dispatch for a release revalidation; and then continued to destination without further incident. This event shook me up. As we were stopped the landing traffic crossed down field in front of us. It was truly a sobering event that could have ended much worse. I think often when flying the line we fear far's more than loss of life. I know I can fall into the trap of worry whether or not I'm legal rather than whether or not I am safe. This incident has renewed my awareness of how quickly this job can turn catastrophic. This incident involved complacency; perhaps a bit of 'get home fever;' and other serious distractions in my personal life that are currently consuming my mind. I have been paired with the same captain for the last 4 trips including 2 days of recurrent. There is a certain comfort level that can develop in working that much with the same person; unfortunately that comfort level can be negative as well leading to the degradation of the professional environment. This flight was the last leg of the trip and we were both ready to be off for a few days. I honestly can't say why she decided to start a takeoff roll without clearance; or why I wasn't immediately aware of our deviation. This has made me realize how a momentary lapse of memory or a short loss of focus can lead to dangerous situations. I plan to internally process this event as a wake up call. Because of the alertness of the tower a potentially serious event was avoided; but I need to take it upon myself to break down the walls of complacency and make sure that my mind is focused on the task at hand rather than on other life situations.

Title: CRJ200 flight crew reports being cleared to line up and wait for traffic landing on an intersecting runway. The First Officer reads back the clearance then reads the takeoff checklist at the Captain's request and the Captain begins the takeoff roll. The Tower notes the takeoff commencing and calls for the reject as the landing traffic rolls through the intersection.
