[NewCandle] Nick's aluminum UFO poop.

[Keith Nagel]

Hi All,

While I'm long past the point of playing with this stuff, I do
remember back in the wooly days of youth playing with rockets.
Aluminum burns good, and it's cheap, and I seem to remember
playing with it a bit after reading an old Amateur Scientist
article about zinc/sulfur rockets. Here's a quick google
result that shows what to me appears to be the members of
the band Pink Floyd playing with said toys, including aluminum

There is also a formula for just aluminum powder and LOX. 

NASA's solid rocket boosters are also composed of aluminum and
oxidizer, as so.

So there's ample opportunity for an amateur to be pooping
molten aluminum all over your yard. But it's probably indicative of
a failure of the propulsion system (incomplete burn).

It could also be an aluminum part of a rocket burning off or failing. 

What did the witness report about the behavior of the UFO?

PS: You could ask around after the local amateur rocket folks,
but frankly I was never that "available" when I was piloting
UFO's about my childhood hometown. Set the controls for the
heart of the sun...
