Winco,
As I have said in my only post during this discussion, any acceptable wing tank leak, which we get airborne with, is highly unlikely to deteriorate suddenly in flight. Even given all the factors you describe. The tank pressure is minimal and protected by relief valves. Any fuel which does leak would stream off the wing due to airflow, so even if the wing tank ruptured the risk of fire would be minimal. We do not accept any leaks in areas where the fuel could gather. Lots of people on here are still missing the fact that acceptable leaks are acceptable because they pose a minute if not zero threat to aircraft safety. This is due to the nature of what is causing the leak and the location of it. These acceptable leaks you are all talking about did not cause the tragic events which have prompted this discussion. Please, one and all, keep the discussion focussed on the real problems.
Thanks
RIP Boys
