BOAC....
Just an answer to your point about the MAN SID readback to tower before departure. This was introduced due to the number of westerly departures that having been given the Honiley depature, then flew the LISTO, and vice versa. Even though they'd read it back correctly! They are the only SID's that require the pre departure check and that is done by individual query from the Air controller. I'm not aware of any moves to incorporate it onto SID plates and thus make it a pilot responsibility to state the SID without being asked. It is handy if you do though. I realise it's a bit unwieldy but it works and incorrectly flown SID's on these departures are down to nil.
