Years ago in another life we had our RWY closed for works. NOTAM'd and marked by white crosses etc. Pilot overflies and lands between a pair of crosses and taxies around the other. When I asked him if he got the NOTAM, he said he didn't bother with them, that's why he overflew first. I asked him if he saw the white crosses. He said yes, and that he made sure he didn't run over any of them. When we came back later, he'd taken off and gone. I called the "local" CASA office to let them know. Their response: "Well he got down safely, that's the main thing". I got the impression that that was as far as it was going to go.
