The three named aircraft left Heathrow on the 13th May and arrived at Jamestown 7h33m later, being refuelled by KB-50s of the 429th Air Refuelling Squadron en route.
I thought I recognised the Fairey hangar in your photo!
Incidentally, the other 3 F-100s overflew Jamestown and continued to Los Angeles, setting a new world distance record for single-engined aircraft of 5835 nm.
