I did these intercepts a quite a few times in the late 60’s & 70’s.
We’d launch 2 F-4’s off the ready cats, we have one on his 6 and the other would come up on his port side.
We’d nod at each other, he’d open his bombbay doors and the guy at the 6 would fly up underneath and have a look to see if he was carrying weapons.
Then we would take up positions at his 9 oclock and his 4 oclock and make obsene jestures ant each other..

That tactic was used against us on one occasion when an F-15 (IIRC) went to investigate the open doors and found a slew of photographers. Pilot hit the speedbrake rather quickly.
