Amos2, do pay attention you old f@rt! We try to make allowances for you geriatrics, even if you do know how to suck eggs already. However, your bad tempered attack on NSEU is unwarranted as he has never claimed to be a pilot, like wot you once was.
Thankfully, we also have technicians and engineers who are well versed in the systems that we have to deal with and they do help with giving us young whippersnapper pilotos some points of reference. Retired old farts like Amos2 and his grumpy old brother, 411A, should at least try and understand a bit better the stuff they are reading whilst their cocoa and slippers are being prepared by their carers.
