Narrative:

We made an emergency landing on sep/xa/98 at XX35 due to engine failure in-flight. Received clearance to land on runway 3L from the tower at nellis AFB. We were heading for laughlin/bullhead, got off course and ended up passing it in the darkness. When we realized this 'mistake' of ours we didn't have enough fuel to turn around and go back. Instead, we headed for the city we saw in the distance without knowing that this was las vegas since we only had a sectional chart over arizona to look at. When we got closer to the city we decided to stay on the inside of the 'south mountains' since our engine was running rough and we wanted to stay close to available emergency landing places. That's when we entered class B airspace without knowing. At this point we were trying to figure out exactly where we were and what frequencys to call up. Then everything happened so fast, the engine started to cut out, we had just found the frequency to nellis AFB and I called them up since we were just about 2 mi away from the base. We declared an emergency, got lined up with the runway and got the clearance from the tower to land. Afterward we called a man named mr X at the FAA there and explained the situation for him. We realized that we caused a lot of problems for the control tower at las and for that we apologize deeply. We are going to take precautionary action and receive recurrency training in night flying so that this 'mistake' won't occur ever again.
