First the big planes got their turn, and they've made the most of it: <i>The World Record Paper Airplane Book</i> and <i>Kids' Paper Airplane Book </i>together have over a million copies in print, and they're still soaring. But now they've got a new little sibling: Pocket flyers Paper Airplane Book, a flyaway impulse book if ever there was one. Developed by the same team of Ken Blackburn and Jeff Lammers, <i>Pocket Flyers Paper Airplane Book</i> features 12 Lilliputian-size models, for a total of 74 planes. The models are about one-quarter the size of the planes in the previous books and are designed with original full-color graphics. There are easy folding instructions for each, as well as special tips on how to fly smaller aircraft. The portable package and its planes are perfect for small spaces: the office, the den, the back of the minivan, drinking establishments. The obsessed among us will try to establish a mini plane world record. The rest of us will be content to just fly these flashy Piper cubs of paper from one side of the room to the other. And with the Microjet, Angelfish, Flying Sneaker, Gargoyle, and Dragonfly, there promises to be a lot of contentment.<br><br>210,000 copies in print.
