My Pilots Pal measures about 8"x10", has hard, blue, cardboard covers front and back, the front bearing the following message in gold letters ... Pilot's Logbook.
I haven't counted the pages tightly bound between the covers, but my first entry - by pen or indelible pencil - was in 2003 and at my present rate of aviating will probably see me through as many years as I wish, or am allowed, to aviate.
It is impervious to power outages or Internet seizures.
