Narrative:

Returning to alexandria airport, nj, from flight to mmu, nj airport had been notamed closed runway 25 during my absence (that morning) for survey. No 'X' on runway visible. Radios failed in flight, so no communication to discover closing. Found out after landing. I should have called FSS for information prior to return, but never expected runway to close during my absence. Airport radio and office operator said he discovered the crew were doing the survey when he arrived to open the office and had not been informed of the scheduled work by the owner until the morning of the survey crew's arrival. If I had checked FSS for NOTAMS or if the runway had had a large 'X' on it, the incident could have been avoided. Callback conversation with reporter revealed the following: reporter says, 'I learned about flying from this--and after 20000 hours of flying.' no notice had been given at the airport and this was a no radio situation, so no chance for unicom to warn pilot. Training flight with departure 4 hours earlier. Fortunately survey crew was not on runway at time of landing. No markings on runway. Small country airport.
