While it's generally agreed there's 5 beautiful female pilots in the Flying Circus, there's a bit of discontinuity in both the film and the promo shots as to who the 5 actually are...

When the 5 planes land, we see this Glamazon Pilot first...

But when all the pilots appear next in front of Pussy, the above Blonde is not one of them...

In some promo shots, there are 5 pilots, and again the 1st Blonde is missing...

These above 5 are the one's who do the gassing of Fort Knox, but in other promo shots there's a short brunette...

And again the Big Blonde from the first screen shot is nowhere to be found...

"This is Champagne Leader..."

"Ready for 'Rock-a-Bye Baby'..."

The Female Pilots release knock-out gas on the army men below...

"The baby is asleep..."

Pussy Galore's Flying Circus is a watershed  moment in FemmeDom, touching off innate fantasies embedded in the male sexual psyche... The male mind boggles at the thought that somewhere out there there may be a Gang of Beautiful WOmen who have joined together in black tights, white belts and boots and go around felling men with Knock-Out Gas under the direction of a Female Authority Figure... Moving towards 1965 and beyond, there will be endless variations on the theme of Female Gangs / Organized Secret FemmeSocieties in the surreal realm of SpyWorld that depict FemmePower in the form of Anonymous Glamazons who first overwhelm men psychologically with their physical beauty, then overwhelm them physically with devious devices to either kill or render the male unconscious... This first foray is rather tame, as the WOmen do not actually confront the men face-to-face, but the attitude & intent are monumental with the WOmen posturing as Perverse Nurturing Mothers who fly above the men, not offering the security of their breast milk, but a streaming noxious gas that will put all the baby boys to sleep... Ultimately, rather than in the James Bond ersatz-SpyWorld, both the costuming and the gassing FEMMEnomena will receive their fullest expressions in the fantasy tv show Batman...
