Rainboe, I agree you won't need an engneer at every stop....BUT some defects do need investigation by a suitably qualified engineer that a 'pilot' even on his great pedastal in the sky would not have any idea about the servicability of or not....so flying it back for maintenance in some cases is not really the option.
Step back and await the flak from the few pilots with B1 and B2 licences!!!
