BTW, fyi I was pax on a flight last year where a narrow body jet airliner touched down/went around in CAVOK conditions, so its not impossible, even if unusual.
I did that last summer onto 33 at BHX, floated a bit too far for my liking so went around, touched the RWY whilst engines were spooling up, pretty much a non-event (was quite good fun though). Night, CALM, CAVOK.
Tower told me that just as I flared there was a bit of a tailwind, about 7kts, so I looped round to land on 15 in the end.
Apparently we only had to pay the one landing fee!!
