Narrative:

Filed IFR flight plan for local instrument approaches with a flight instructor. Deported sgs airport (within 'enhanced' class B airspace, under a class B shelf) VFR, then received the IFR clearance once airborne. Once back on the ground I began to wonder if the NOTAMS allowed me to depart in the enhanced B airspace VFR with a flight instructor, then receive the IFR clearance airborne. I believe the NOTAMS were unclear on what was and wasn't allowed at that time. Suggest NOTAMS be written more clearly. Happened during restr flight times following terrorist attacks.
