That's pretty cool !!!!! I've worked for five years (2003 - 2008) at Lockheed Martin in Fort Worth during the development phase of all three variants of the F-35. I was responsible for the produceability of the In-flight-opening-doors. Some of the doors are for example the landing gear doors.

Highlight was December 15, 2006 when I witnessed First Flight of the F-35 Lightning II.
