In the first Swifty book, Jimmy Robinson finds the wreck of an aeroplane in the back corner of a hangar. To his amazement a voice comes from the wreck asking Jimmy to mend him so that he can fly again, and in return he will teach Jimmy how to fly! Jimmy does the job and this was the beginning of their many adventures together described in book one. In this book Swifty starts to lose his magic which means he will have to go to the Magic Aircraft Factory, which is near the South Pole, to get it fixed. This book tells you all about the exciting adventures Jimmy and Swifty have on the way to the South Pole and back, even finding a stowaway on the journey!
