For discussion of everything rum and uncanny, from cryptozoology (mysterious or out-of-place animals), UFOs, high strangeness, etc. Following in the footsteps of Charles Fort and all those inspired by him, like the field of anomalistics.

As this community is on Feddit.uk it takes a British approach to things but it needn't be restricted to the UK - if it's weird and unusual it probably has a home here.

It was 27 October 1954, a typically crisp autumn day in Tuscany. The mighty Fiorentina club was playing against its local rival Pistoiese.

Ten-thousand fans were watching in the concrete bowl of the Stadio Artemi Franchi. But just after half-time the stadium fell eerily silent - then a roar went up from the crowd. The spectators were no longer watching the match, but were looking up at the sky, fingers pointing. The players stopped playing, the ball rolled to a stand-still.

Play was suspended because spectators saw something in the sky, according to the referee's match report.

The incident at the stadium cannot simply be interpreted as mass hysteria - there were numerous UFO sightings in many towns across Tuscany that day and over the days that followed. According to some eyewitness accounts a ray of white light was seen in the sky coming from Prato, north of Florence.

It is a fact that at the same time the UFOs were seen over Florence there was a strange, sticky substance falling from above. In English we call this 'angel hair'.

Diborane exhaust particulates are sticky according to the wiki article on ZIP fuels.

Silane is a gas like methane but with a silicon atom instead of a carbon atom, and burned silicon is glass/sand/quartz. Burning that gas as fuel can make little balls of molten glass in the exhaust.

A fuel of silane and diborane would make sticky glass "angel hair".

A rocket that uses it would also re-light reliably, making that fuel mix a good candidate for use in a Reaction Control System. With a powerful enough RCS you can do things like this:
