I think the issue regarding the size is more that there isn't enough space to add enough fuel, a full set of avionics such as comms, radar, IFF etc and get a pilot without a growth hormone deficiency crammed into it (perhaps they are using that monkey when it comes back!). Size doesn't matter with stealth technology at all - it's all about which way EM radiation bounces off it. It looks like a JJ Abrams prop to be honest. Actually not even that credible. Regarding virus and software attacks on aircraft (military at least) - it's all a load of JJ Abrams style "let's inject a virus into the core" horse shit.
