PID stands for Proportional, Integral, Derivative, it is a type of feedback control. I'd be surprised if the vehicle didn't have one of these and it itself is the source of the problem.
Actually, the reason the Japanese did not rapidly surrender immediately after Hiroshima is more complex. Bureaucratic inertia insured a pretty slow response. (The leaders did not even meet for two days following the attack, and debated the issue for half the day) The Emperor himself had been pushing for peace for some time following the Japanese defeat at Okinawa, but the Allied insistence on unconditional surrender, as well as political subterfuge by Stalin (who played on Japanese hopes of Soviet assistance while preparing his own attack against Japan), fed fire to an already heated debate among Japanese leaders. In an all-too-familiar story, political infighting prevented the country from taking prompt, sensible action.
> For a brand new product vs an iconic powerhouse, that is little short of amazing.
I look at it the other way: a brand new product SHOULD be doing well compared to a similar product that is three years old and is largely unchanged.* "Iconic powerhouse" or not, a new product should be doing SOMETHING other than just sitting there getting crushed.
* Other than GPS, videorecording, and 3rd-party apps--which OTHER smartphones had BEFORE the iPhone was even out (so their introduction, while nice, wasn't earth-shattering)--little new of substance has been added to the iPhone since its introduction in January 2007. (Plus faster networking and a better camera and more storage, but that's just "it gets incrementally faster/better over time" like ANY technology.)
Again, the Flyer was powered with a gasoline engine IIRC. A powered heavier-than-air machine is an "airplane", not a "glider". It doesn't matter if it requires ground-based infrastructure to launch. So yes, they invented the first airplane that could do figures of eight.
As for Joe Sixpack, he's a moron who probably also believes the Earth is 6500 years old and that Sarah Palin would be a good President even though she thinks Africa is a country (or, he's a moron who thinks Barack Obama is a great President who's going to keep his union job secure). What he thinks about who invented the first airplane is irrelevant to anyone with an education.
There are many approaches that are MOSTLY the same effect, but not quite. The nice thing about using actual separate processes is that a nasty memory corruption bug only kills the one process. With threads, one scribbling on memory can easily take them all out. The drawback is that it's a bit harder to share a lot of state (though there are many options for that).
Going the speed of light is bad for your age.
