The Boeing 707 was a great success, but it was probably most successful in it’s military guises. Known internally at Boeing as the ‘B717’, a designation that was re-used for the MD9 after the Boeing/McDonnell-Douglas merger. The militarised version had numerous military designations and although ageing, many are still in service with many of the worlds militaries today.
It is likely that a number of these will remain in service for an other 20 years or even longer, there are airframes that potentially could actually be flying antiques in the truest sense of the word.
Why was the aircraft such a success, it did what it said on the tin – the versatility and sturdiness of the militarised version have made it a winner. Operated in many varying roles by many air forces, the aircraft has a proven track record – delivering as they say a lot of bang for each buck.
The primary variants C, EC, KC, NC, RC, OC and WC only explain some of the geneology of the type. There were also the C137, E3, the E6 and a number of other variants – but ultimately these were all variants of the original Boeing 707.
All you ever wanted to know is covered in the book, it is a pretty definative work – very readable and great value. If you have an interest in the Boeing 707 or the C135, this book is a must extremely detailed and some fantastic illustrations just completes the book.
