Narrative:

We were clear to taxi to runway 26 from the local FBO in dxr, ct. As we were getting close to the beginning of runway 26, we were clear to taxi into position and hold. As a copilot, I started the before takeoff checklist. As soon as the checklist was completed, we started the takeoff roll. As we moved about 500 ft we saw an aircraft, that just landed on the intersecting runway 35, cross in front of us. This aircraft I would say was about 1000 ft from our citation. Luckily we were far from them and we continued with the takeoff. Later we realized we took off without a clearance. Next time I will pay more attention to ATC.
