I don’t believe I had seen this on this thread. Seems a shame to waste the assets by storing them.
The Netherlands is to place its Lockheed Martin F-35A Joint Strike Fighter test aircraft into temporary storage, pending a final decision on how to replace its air force's Lockheed F-16 fighters.
Newly appointed defence minister Jeanine Hennis-Plasschaert announced the decision to park the test assets in a letter to the Dutch parliament on 4 April. A first example - delivered in late 2012 - and a second, expected to be handed over in mid-2013, will be stored at Edwards AFB, California, where they will be kept in airworthy condition and flown occasionally by US Air Force pilots. The effects of the decision will be discussed with the F-35 Joint Program Office.
