Two excellent books have recently been published specifically about the 27th Bombardment Group (L) and its personnel in the early stages of World War II:
"Operation PLUM - The Ill-Fated 27th Bombardment Group and the Fight for the Western Pacific", by Adrian R. Martin and Larry W. Stephenson. Information about this book can be found HERE. It is available from the publisher and other leading booksellers. A sample chapter can be found on the publisher's website.
