Smudger,
A single rad alt failure caused a hull loss and fatalities on a Boeing 737 recently. A duel rad alt failure on this airbus resulted in some scratched paintwork.
Me thinks Airbus wins on this occasion.
Until these biased people start to realise that safety is just the sum of the aircraft design and the pilots flying it we'll continue to get this biased rubbish.
I have 7000 hours with an approximate 50:50 split Airbus narrow body and currently Boeing wide body and have thoroughly enjoyed flying both. They're just tools to do a job and the better you know them, the safer you are.
