Are you sure you have the correct aircraft?<p>&quot;The planes have been flying (mostly bug free) for over 10 years now.&quot;<p>Considering first flight was in December of 2006 there&#x27;s no possible way it could have been flying for a decade as of today.  Also that was the maiden flight, not a take-delivery-first-production-flight, but the first flight ever.<p>As for bug free, I&#x27;d beg to differ:
* On 18 January 2013, the F-35B was grounded after the failure of a fueldraulic line in the propulsion system on 16 January.
* On 5 June 2015, the U. S. Air Education and Training Command Accident Investigation Board reported that catastrophic engine failure had led to the destruction of an Air Force F-35A assigned to the 58th Fighter Squadron at Eglin Air Force Base, Florida, on 23 June 2014.
* On 23 June 2014, an F-35A preparing to take off on a training flight at Eglin Air Force Base experienced a fire in the engine area. The pilot escaped unharmed. The accident caused all training to be halted on 25 June, and all flights halted on 3 July. During the incident investigation, engine parts from the burned aircraft were discovered on the runway, indicating it was a substantial engine failure.<p>And a report issued in 2013 stated these amongst other major problems:
* Current aircraft software is inadequate for even basic pilot training.
* Ejection seat may fail, causing pilot fatality.
* Several pilot-vehicle interface issues, including lack of feedback on touchscreen controls.
* The radar performs poorly, or not at all.
* Engine replacement takes an average of 52 hours, instead of the two hours specified.
* Maintenance tools do not work.<p>&quot;Bug free&quot; I guess if those are acceptable criteria for a government defense platform that has racked up over a trillion in cost and has yet to perform much, if any, real-world value.
