Narrative:

Flying on an IFR flight plan from aln to hef; and landing without incident. Taxiing in; tower told us to contact departure for clearance IFR. We refueled and filed a new flight plan (IFR) back to aln. At approximately XB30-XB40 sitting at the end of runway 16L we tried multiple times to contact departure for a clearance. Trying both departure; tower and ground frequency we could not reach anyone. We then departed VFR to pick up our clearance. We established communication with potomac departure and at that point was told that we needed to contact them by phone and that we entered into restricted airspace. After departure we climbed to 2000 ft 1-1.5 miles off the end of the runway; made a left hand turn to the down trying to establish communication with departure.
