Despite talk that it had cancelled the deal, the US Air Force on Friday pledged itself to a contract to buy up to 18,000 iPads. Air Mobility Command has agreed to a $9.36 million pact that will see Executive Technology give C-5, C-17, C-130, KC-10, and KC-135 crews 32GB Wi-Fi iPads to use as replacements for their paper flight manuals and similar guides.
