So did you get an answer Dick and in your opinion is it something that could have dwarfed Lockhart River? I think the incident that could have dwarfed LR was the 737 effectively autolanding in the fog at MIA, but that is very much in the public domain.
There is a difference between making statements about safety issues and not reporting an incident that has the potential to "dwarf Lockhart River". The original statement made by TB was either hyperbole or BS.
