Learning from the Boeing 787's broken software.

Earlier this year Boeing 787 maintenance engineers were given some new instructions by the FAA (The US government's: Federal Aviation Authority).

To ensure I get what I want, I've taken some time and documented the following requirements for my new clock. They list what I want from the timepiece, and also what I don't want or need. Have a read through, and hopefully you'll see what it is I'm after. A new clock should be developed for my new home in London. The clock will need to: - Display the time. - Display in roman numerals and modern  'arabic' numerals . - Be accurate enough for household use - approx' to with in a few minutes. - Be ornamental - preferably with a intricately styled clock face. - Have a traditional square brass clock face - Be construct
