"Do you go under the name of CRAN on PPRuNe?' And if the answer is yes, the next question is "So why do you pretend to be someone else on there?". It's not like anything that CRAN has posted on this thread is particularly contentious but I feel uncomfortable about someone who posts under a nom de plume.
Looking at his posts I can see why you ask, although the fact he once asked how hard a Bo105 would be to fly without hydraulics doesn't fill me with confidence!
