I have a streak of nostalgia that runs especially deep when it comes to toys or children’s books. These balsa wood gliders, made since 1926 by Guillow’s, bring back a whole flood of emotion. Every summer my brother and I would end up with a couple of them. I remember my favorite one being the Sky Streak. The rubber band made the arc of flight longer and faster than any of the others. And the propeller added a third element into the design that made it feel not quite so bare bones. My only frustration was at how brittle the balsa wood was, and that if you were even the slightest bit impatient, there went your toy. The fact that these are still in production is good news.
