Human error

Well I have news for you amos2, dedication, motivation, training and striving to achieve high standards does not guarantee an individual will not make errors. How those errors are managed is important. Unless of course it is someone like you who never make errors. BTW I have 35 years in the industry flying many types from small singles to jet transport aircraft - and I still make errors.
