Just what is WOOMERA? Well it's the strangely-named Earth Base located in Australia seen in the very first SWORD comic strip in SOLO 19 [24th June 1967] pictured above. It complements the Moon Base in the Ocean of Storms on the Moon. Both are admistered by SWORD Commanders Rapier and Sabre [aka Woodsy and Wotan! hee hee].
So why Woomera? I had to check ...and then it all made sense. Woomera was and is a military area, where rockets and missile tests are carried out like the British Blue Streak. It will have been known to the [unknown] writer of this very first SWORD strip. I imagine it sounded fairly exotic. Maybe it featured in kids' magazines like Look and Learn, World of Wonder and so was known to kids in 1967 [anyone know?]. I imagine the writers considered and discounted Cape Kennedy and the British missile area High Down for whatever reason.
Amazingly, the real Woomera base is still there and online! There's a village and heritage centre [below] and merchandise available! [pictures courtesy of Woomera Base]
Rapier and Sabre would have been thrilled!
PS. WOTAN mentioned the Woomera card in the Tri-ang LUNA-CY game. It's pictured below and the Mighty Wotan's covered it in full previously on the blog.
