On one of my first B727-100 flights as an F/O my training captain showed me how to enter a circuit at high speed (this was of course before there was speed control, 250 below 10,000 and FOQA). Request a high speed approach at Darwin and entered a long downwind at 390 indicated. All worked well. I do recall tho that my brain and heart landed long after the aeroplane!
Years on the wonderful 777 aside, getting a command on the 727 was simply the best thing ever. Yes....thanks Boeing!
