Narrative:

Another pilot and I took off from nashua, nh, (ash) just before the tower at nashua closed for the night. We intended to enjoy a beautiful evening, and to see if a newly repaired door and autoplt coupler was working properly. We flew west to keene (een) then tracked east to ash. All system appeared normal except we wanted to see the couplers work on a localizer. We therefore lined up with mht's runway 35 to test, and all worked fine, so we decided to go nashua for a touch-and-go. With all the turning and looking at navigation readouts, we found ourselves momentarily disoriented with respect to geography, but we quickly located ash and did the touch-and-go. During the downwind, we talked with other ash traffic on tower frequency, as is done when the tower is closed. We spotted traffic ahead of us landing, and other traffic announced that they had spotted us. During the actual touch-and-go, I was primarily occupied with assuring spacing with the traffic who had landed ahead of me and was clearing at the end of the runway. I was not referencing my instruments, but was mostly concerned with traffic. We completed the touch-and-go, then departed the area to fly for awhile, to enjoy the evening and check a few more approach modes, etc. (This was why I brought along another pilot. I was going to be heads down from time to time, and I'm new to this area, so another set of eyes who knew the area would be useful and safe.) we decided to return to ash and landed without incident. Why am I writing you? Because I've the very uncomfortable feeling that the touch-and-go wasn't at nashua! When we full stopped at ash, we remarked how it looked darker than when we tough- and-go'ed. With all the traffic lookout, I never really noticed, but I believe we may have inadvertently landed at another airport, maybe manchester, whose tower would be where nashua's is in relation to the runway, etc. During the touch-and-go, I was talking to nashua traffic, and spotted traffic announcing themselves, and was specifically spotted by another nashua traffic pilot -- all indications were that everything was normal, until we came back to nashua to land. If I landed at manchester, then I inadvertently invaded their air traffic area, and did a touch-and-go on their runway without talking to tower! Although the touch-and-go was completely safe and didn't threaten traffic spacing, etc, it would still be a grossly unprofessional action.

Title: PLT OF SMA MADE NIGHT TOUCH AND GO AT ARPT, THOUGHT IT WAS ASH BUT MAY HAVE MADE THE TOUCH AND GO AT MHT.

Narrative: ANOTHER PLT AND I TOOK OFF FROM NASHUA, NH, (ASH) JUST BEFORE THE TWR AT NASHUA CLOSED FOR THE NIGHT. WE INTENDED TO ENJOY A BEAUTIFUL EVENING, AND TO SEE IF A NEWLY REPAIRED DOOR AND AUTOPLT COUPLER WAS WORKING PROPERLY. WE FLEW W TO KEENE (EEN) THEN TRACKED E TO ASH. ALL SYS APPEARED NORMAL EXCEPT WE WANTED TO SEE THE COUPLERS WORK ON A LOC. WE THEREFORE LINED UP WITH MHT'S RWY 35 TO TEST, AND ALL WORKED FINE, SO WE DECIDED TO GO NASHUA FOR A TOUCH-AND-GO. WITH ALL THE TURNING AND LOOKING AT NAV READOUTS, WE FOUND OURSELVES MOMENTARILY DISORIENTED WITH RESPECT TO GEOGRAPHY, BUT WE QUICKLY LOCATED ASH AND DID THE TOUCH-AND-GO. DURING THE DOWNWIND, WE TALKED WITH OTHER ASH TFC ON TWR FREQ, AS IS DONE WHEN THE TWR IS CLOSED. WE SPOTTED TFC AHEAD OF US LNDG, AND OTHER TFC ANNOUNCED THAT THEY HAD SPOTTED US. DURING THE ACTUAL TOUCH-AND-GO, I WAS PRIMARILY OCCUPIED WITH ASSURING SPACING WITH THE TFC WHO HAD LANDED AHEAD OF ME AND WAS CLRING AT THE END OF THE RWY. I WAS NOT REFING MY INSTS, BUT WAS MOSTLY CONCERNED WITH TFC. WE COMPLETED THE TOUCH-AND-GO, THEN DEPARTED THE AREA TO FLY FOR AWHILE, TO ENJOY THE EVENING AND CHK A FEW MORE APCH MODES, ETC. (THIS WAS WHY I BROUGHT ALONG ANOTHER PLT. I WAS GOING TO BE HEADS DOWN FROM TIME TO TIME, AND I'M NEW TO THIS AREA, SO ANOTHER SET OF EYES WHO KNEW THE AREA WOULD BE USEFUL AND SAFE.) WE DECIDED TO RETURN TO ASH AND LANDED WITHOUT INCIDENT. WHY AM I WRITING YOU? BECAUSE I'VE THE VERY UNCOMFORTABLE FEELING THAT THE TOUCH-AND-GO WASN'T AT NASHUA! WHEN WE FULL STOPPED AT ASH, WE REMARKED HOW IT LOOKED DARKER THAN WHEN WE TOUGH- AND-GO'ED. WITH ALL THE TFC LOOKOUT, I NEVER REALLY NOTICED, BUT I BELIEVE WE MAY HAVE INADVERTENTLY LANDED AT ANOTHER ARPT, MAYBE MANCHESTER, WHOSE TWR WOULD BE WHERE NASHUA'S IS IN RELATION TO THE RWY, ETC. DURING THE TOUCH-AND-GO, I WAS TALKING TO NASHUA TFC, AND SPOTTED TFC ANNOUNCING THEMSELVES, AND WAS SPECIFICALLY SPOTTED BY ANOTHER NASHUA TFC PLT -- ALL INDICATIONS WERE THAT EVERYTHING WAS NORMAL, UNTIL WE CAME BACK TO NASHUA TO LAND. IF I LANDED AT MANCHESTER, THEN I INADVERTENTLY INVADED THEIR ATA, AND DID A TOUCH-AND-GO ON THEIR RWY WITHOUT TALKING TO TWR! ALTHOUGH THE TOUCH-AND-GO WAS COMPLETELY SAFE AND DIDN'T THREATEN TFC SPACING, ETC, IT WOULD STILL BE A GROSSLY UNPROFESSIONAL ACTION.
