OK,
SAS - a quick and simple question ...
You fly as FI for an hour with someone as a revalidation "training flight" but (for reasons best known to yourself) you decide it is a "test", that they have failed and you therefore decline to sign their logbook.
In these circumstances, how would you suggest you should each record the flight in your respective logbooks?

PS I'm going flying now - there's plenty of lift in the air today ...
