Ok I will admit this is hardly my usual fair but you know what I dont care! My parents tidying up their house found this book from my old collection even though i have not lived there for over 20 years (oops you mean a book escaped me....) and I love it. Its part of the Ladybird book series published from the time when it was based in Loughborough close by (if you travel there by train they still have it under they station sigh saying the Home of Ladybird Books) Anyway the book is from 1969, yes it is older than I am and its fascinating. What I love about this book is that even though its aimed at a younger audience it still has no shame of diving off in to complex calculations demonstration the lifting power of a hover craft. This book to me epitomises an era where even for the youngest reader complex principles and ideas where not shied away from and as such to me it has the ability to appeal to all ages of a technical leaning.
So for all 51 pages this is a brilliant book and a wonderful little diversion.
So yes in moving my book collection I stumbled across his Ladybird book - I after reading it again ( I cannot remember the number times I went through my collection of these books) I realise how actually very technical it is - for a book so slim it even goes in to the calculations needed to provide the appropriate amount of lift. I guess children's books from the past tried to be a lot more educational I guess. So yes an impressive little book
