Very true, em.
Read a book entitled "Empire of the Skies" by James Hamilton-Paterson. There you will see described a number of these "old crates" which were developed and built by the various aircraft manufacturers which the UK had after WW2 until the late 60s. You will also learn how that industry was decimated by government inaction, prevarication and outright obstruction and you will wonder how some of these old crates managed to get into the air at all.
The Avro Vulcan was designed sixty years ago but remains, along with the Gloster Javelin and the EE Lightning, one of the finest aircraft of its type. To describe it as an old crate defies belief.
