They may be bringing Raki to trade for jet fuel.....although both are similar.
BTW I have a photo of the original F4H-1 I took as a kid at an open house at Edwards AFB in the 50s. I can't post pics here but if anyone wants it, let me know, PM or otherwise, and how to get it to you. From same 50s display also have F-107, F-105, F-8, A-4 & B-52/X-15 combo. Would like to see 'em posted here.
