Even so, if it is true, it shows that the software just wasn't intelligent, or, more likely, informed enough to cope with the situation. It didn't know about the trees, but if it did know, it should have allowed a low-angle climb to clear them. It must be a general principle that if a quasi-intelligent system does not know a key fact, it may implement a dangerous sequence of actions. What you don't know will kill you. -- This is my travelling signature, adding no superfluous mass.
