But as the buck stops with me my main concern, as your relatives would be the first to tell me, is that nothing kills you!
But isn't that something you do before
sending someone off to fly solo? Or are you concerned that something really dangerous happened during the first solo, which the student might forget about if you don't debrief him on the spot? If so, then fair enough. To me it sounds a bit over the top, but of course, you know your students best.
