Narrative:

I filed an IFR flight plan from stl to wright-patterson AFB ffo. During the descent we were handed over to day approach, where they vectored us on a right base for 24R at day. We were handed over to the center tower where they cleared us to land on 24L. Once we landed we discovered we landed at the wrong airport. Reason crew believed it was correct airport. I looked at the global navigation equipment and it showed that the airport was at our 1 O'clock and 20 NM. Looking outside I saw a large airport with the same runway layout as wright-patterson. I did not cancel or advise approach that I saw the airport. Center, approach and tower all believed I was landing at day. During the vectors for the right base I told the copilot to set in the ILS frequency for 23R to confirm the runway. When we were handed to day tower the copilot called the tower as wright-patterson. Day tower did not correct the mistake and cleared us to land on 24L. We did not have to change ILS frequency for the right side to confirm the runway. Approach put us in front of traffic that was 2 mi away and traffic following us was right behind us, eventually putting us on a high short right base keeping us busy until landing. Airports look similar in runway layout and length. Airports are 10 NM from each other.

Title: ATX FILES IFR TO WRIGHT-PATTERSON AFB. APCH HANDOFF TO TWR, VECTORED TO LNDG AT DAY.

Narrative: I FILED AN IFR FLT PLAN FROM STL TO WRIGHT-PATTERSON AFB FFO. DURING THE DSNT WE WERE HANDED OVER TO DAY APCH, WHERE THEY VECTORED US ON A RIGHT BASE FOR 24R AT DAY. WE WERE HANDED OVER TO THE CTR TWR WHERE THEY CLRED US TO LAND ON 24L. ONCE WE LANDED WE DISCOVERED WE LANDED AT THE WRONG ARPT. REASON CREW BELIEVED IT WAS CORRECT ARPT. I LOOKED AT THE GLOBAL NAV EQUIP AND IT SHOWED THAT THE ARPT WAS AT OUR 1 O'CLOCK AND 20 NM. LOOKING OUTSIDE I SAW A LARGE ARPT WITH THE SAME RWY LAYOUT AS WRIGHT-PATTERSON. I DID NOT CANCEL OR ADVISE APCH THAT I SAW THE ARPT. CENTER, APCH AND TWR ALL BELIEVED I WAS LNDG AT DAY. DURING THE VECTORS FOR THE RIGHT BASE I TOLD THE COPLT TO SET IN THE ILS FREQ FOR 23R TO CONFIRM THE RWY. WHEN WE WERE HANDED TO DAY TWR THE COPLT CALLED THE TWR AS WRIGHT-PATTERSON. DAY TWR DID NOT CORRECT THE MISTAKE AND CLRED US TO LAND ON 24L. WE DID NOT HAVE TO CHANGE ILS FREQ FOR THE RIGHT SIDE TO CONFIRM THE RWY. APCH PUT US IN FRONT OF TFC THAT WAS 2 MI AWAY AND TFC FOLLOWING US WAS RIGHT BEHIND US, EVENTUALLY PUTTING US ON A HIGH SHORT RIGHT BASE KEEPING US BUSY UNTIL LNDG. ARPTS LOOK SIMILAR IN RWY LAYOUT AND LENGTH. ARPTS ARE 10 NM FROM EACH OTHER.
