Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Had a visitor today who used to work for a large Steel company, pre-retirement he was a specialist in ultrasonic examination of produced steel. he was talking about stress cracks in rail tracks, cracks in reactor pressure vessels and the time they were given unloaded reactor fuel tube material to test to see if it was possible for them to find a hole 15 thousandths of an inch across that had been made in the material. They explained that it would not be possible at steel production speeds of 20 feet per minute.  The Nuke people said that wouldn't be a problem as their tube speeds were measured in inches per hour.

Any idiot can face a crisis - it's day to day living that wears you out.
