I know I wouldn't have volunteered to be the first on that one unless I had performed a full audit of the design, manufacturing and maintenance organisations. Even then I might have still been wary. Things I know I would have been on the look-out for in those areas would be more with the design, manufacture and maintenance processes and procedures employed by the organisations, proof that these were followed and that a "Safety Culture" existed in the organisations concerned. Language and tools are hardly an issue. -- Paul E. Bennett ................... Transport Control Technology Ltd. +44 (0)117-9499861 Going Forth Safely
