Why Did the Gemini Rockets Burn Clear Flames?

All the rockets from the Apollo era launched on a column on fire, except the Titan.

The Titan II missile that launched the Gemini missions into orbit was the only Apollo-era rocket to use hypergols in its first stage, which had the very aesthetically interesting side effect of burning a clear flame.

For more on the Titan, check Vintage Space for the latest article on how a missile was repurposed into a manned launch vehicle. (The article will be live Saturday morning - check back for it!)

And there's loads of other olde timey space to dig into on Vintage Space in the mean time!

And of course, more videos about Gemini, including why it made that awkward launch sound.
