I regret to have to say that, as I found upon reading page 31 ( I think) there is a degree of: 'verbosity and quantity' in this discussion which keeps surging on. Self opinionation in as closed an area as a cockpit can be remarbably destructive and hardly conducive to babytalk, whatever that may be, to quote Nubar Gulbenkian. Sometimes I really am glad that I am just a retired Tyrannosaurus Captain (but a Rex for all that) and not a simply an old Diplodocus.
