F-001 (FMS 09-5008) took the skies for the first time on 6 Aug'12, and was delivered to the Koninklijke Luchtmacht (KLu, Royal Netherlands Air Force) on 25 July 2013, even before the Dutch government decided for an F-35 order! It was assigned to the 31st Test and Evaluation Squadron at Eglin AFB (FL) and carried the (USAF) OT tailcode during its test program. After the 31st TES, the F-35A was transferred to Edwards AFB (CA) where it joined the 323 Test Squadron. Here it is seen blasting away over the Edwards runway for another test mission.
