I always make my students fill out the first few pages in pencil, so that they don't mess up the additions or fill in the wrong boxes and totals.
And remember a paper logbook is like a diary, something to look back on with fond memories, to be treasured.
I had two stolen long ago when left in a van. Fortunately they had already passed through the hands of the CAA for licence issue.
But they had a lot of memerable night flights and it felt like the death of a pet when they went.
Good idea to make a photo copy or photograph pages with mobile occasionally.
