What strange is, if you read the article, an Iranian engineer claimed that it was GPS spoofing, but the US claims it's primary means of navigation is an inertial navigation system (which seems highly believable given up sketchy GPS can sometimes be).
Plus the Iranians have a video of it smoothly landing at an Iranian airbase (which completely discredits the US's assertions that it crashed, and broke up).
