Good pic. Flaps/slats down, nose cocked up...the Lawn Dart is going slooow to stay behind the Hercules. C-130s can fly fast enough to do IFR with such as Hornets, but must be a speed restriction when they have the ass end open.

Fast-forward to 15:40 on this video to watch an F-105 try this sort of low-speed rendezvous with a B-29, during the early days of experimental air-to-air refueling.

Just a guess, but I think the B-29 was probably moving quite a lot faster than the Herky-bird in your video, yet observe how unstable the F-105 is at that speed.

I assume a big difference between then and now is computational aerodynamics used in the design of the F-18. The F-105 was designed by guys with slide rules.
