Narrative:

I used all radio announcements prior to takeoff, did not hear any aircraft on radio inbound for landing. On takeoff roll, sighted aircraft passing close by on my left at same altitude, tried to contact on radio and on the ground later without success. Do not know if he was on short final and diverted.
