TW50,
You're welcome. I have no idea why PPRuNe persists in blocking the "site that shall not be named", when it is so easy to bypass the block.
I'm eagerly following your installments. Really good stuff, but I have a question:
Whilst the overwings greatly extended range and, hence, flexibility of route planning there was one important safeguard to observe. If there was any malfunction in the fuel feed from the overwing tanks into the main engine system then, for diversion planning purposes, the whole of the contents of the overwings must be considered unusable. This meant that the planning for diversion must be based on internal fuel only.
This passage seems to imply that the overwing tanks were of no value. Could you expand on you description?
