A spate of sightings followed the initial report and an Air Force Skyhawk was put on stand-by to investigate any positive sightings.
On 8 July 1968, an A-4B Skyhawk piloted by LT William T. Reinders, USNR, crashed after takeoff into a Glenview home, killing a 13 year old girl.
Nevertheless, once it entered production it proved to be as good as the British versions, and along with the Martin B-57, its original target, the J65 went on to power versions of the North American FJ Fury, Douglas A-4 Skyhawk, Republic F-84F Thunderstreak, and the two Lockheed XF-104 Starfighter prototypes.
