TH, didn't have time at first.
Once Stanley was open the Herc freighter would depart ASI with the Long Herd in company. A while later the Short tanker, a Victor, would depart and at a 'short' distance from ASI would refuel the long Herc which would already have refuelled the freighter. The two Hercs would continue to the long refuelling bracket, top up Herc and return to ASI. The freighter could then reach FI and, if necessary, divert to Uruguay.
The northbound freighter was unrefueled.
I am sure some Herc guys can fill in any blanks.
