On the subject of spelling, this book has more spelling mistakes than I've seen for a long time.
Lemella hangars, Costal Command, Nordon bombsite, plus some 30 or so
misspelled airfields, e.g. Arbroth, Turnhill, Neatheravon.
There is a photo of a Lamella, which sadly is an 'E' type.
Some of the information has come from Wikipedia, hence we find that Skipton and Tilstock were FIDO sites. (They certainly were not.)
We also have Brigg as an airfield in 1 group (no such station).
It's a good read, but mistakes like these are unacceptable, there are many authorities on the subject who could have proof read this document and improved it no end.
An opportunity lost.
