Perhaps a more important subject is a zero-zero landing
for those extremely rare, but possible, emergency situations (such as fuel leaks and un-forecast extremely widespread fog) when you absolutely must land regardless of weather conditions.
Any nonstandard operation by definition carries more risk, which is one of the reasons airlines don't do zero-zero departures, and their zero-zero landings
are made only with special equipment and specially trained crews.
for GA are almost certain to follow.
We would fly for an hour and a quarter and then swap places, tormenting one another with weird approaches, partial panel, broken radios, ridiculous holds and even zero-zero landings
. It was great fun, inexpensive and we worked up to a very high proficiency level.
