Review # 1 was written on 2014-10-09 00:00:00 Richard Jackson A very large format book with some fantastic photos and interesting text. This book was published in 2000 so there should be a "First Fifty Years" by now! For anyone interested in the conquest of space over the last few decades this provides a fascinating introduction.

Review # 2 was written on 2011-03-03 00:00:00 Paul Whomsley Airplanes have separate parts for lift (the wings), and for thrust (the propeller or a jet engine). For a flying animal (there have been four taxons: insects, pterosaurs, birds and bats) a jet engine is too hot, and a propeller is a kind of a wheel, which never evolved in animals: how would you supply it with blood? So birds and bats must use their wings for both, and the much bigger airplanes don't have to.
