Narrative:
We were cleared for takeoff on runway 30 at iad. The captain and I scanned the arrival area for our runway; taxied onto the runway and began the takeoff roll. As we accelerated through 60 KTS; the captain said 'look at this.' I looked up to see an rj passing over us (approximately 150 ft) on landing approach to runway 1L. We continued a normal takeoff and flight to ZZZ. I don't know if this is acceptable separation at iad; but it looked too close to me. We checked the approach path for our runway; but; knowing that they were landing on runway 1L and 1R; we should have been more observant of the approach path to runway 1L.
