Is there any truth in Private Eye's observations on p29 of issue 1204? Is it normal to have redundant software written by different companies in the commercial aerospace industry?
AFAIK when Airbus went FBW they used at least two software houses - from rusty memory Boeing's 777 design timetable was compromised by going down the same route, so they switched and just used the one company. But we are talking Flight Controls not Powerplant, so I suspect it has little relevance to this accident.
