The Bell 47 Helicopter Story (by Robert S Petite and Jeffrey C Evans)

Bell 47 definitive record

This book is one of those comprehensive, well written and well produced systematic records of a type history. The Bell 47 deserves such a record, even if you are not a helicopter fan, as it was the first mass produced rotorcraft, really. .Congratulations to the authors. As a side note, I wonder how I waited until 2026 to discover this masterpiece, apparently released in 2013.

Bell 47 Encyclopedia
