Switches
My first three aircraft were Trident, VC 10 and DC 9.
The Trident switches were opposite to the VC 10 and the DC 9 had the windshield as datem....above one way, below the opposite.
The Iron duck had a four engine flame out...engineer with Delhi belly had an urgent call of nature - if you can call a curry natural - during climb - did the leaving the panel checklist which was switch all of the fuel pumps on (he was cross feeding).
In his panic he turned them off.
Engines continued to suction feed which had a limit of somewhere around 25 grand and they all flamed out as the climb continued.
We had two RATs...hyrat and elrat...which took a couple of minutes to come on line during which there were no flying controls.
All ended happily and engines got some sort of commendation iirc for getting the engines restarted.
