An Ode to Astr0

[JRod]

I could be wrong, but if I recall correctly Astro PM's with Zaphod led to more perhaps a sighting.

Keeping Astr0's post in mind plus others(ie a recent 4chan post), I do believe many of what we have seen especially triangles are of human origin, while the traditional saucers/hamburgers are more likely to be NHIs.
