The 1st prototype aircraft (#01567) was taken to the Paris Air Show in 1975. This picture was taken in June, just before the Air Show, at Bitburg AB Germany. [Photo by Lt. Col. L. Danner]

The 2nd YF-16 prototype (#01568), seen with a load of 4 Sparrows, including 2 on the wingtips. Given the absence of a radar (the pointy nose was later enlarged to accomodate the radar), this configuration seems odd. [USAF photo]
