That's really bad weather.

Can "transparent aluminum" be far behind?


You're behind the times. Transparent aluminum is commercially
available, I have a sample on my desk. It's expensive - $10/sq. in -
but more bulletproof than armored glass and half the weight. Google
aluminum oxynitride or ALON.

Star Trek 4 came out in 1986. The first patent for aluminum
oxynitride as transparent aluminum - from Raytheon, patent 4720362 -
was filed in 1985 and granted in 1988.

Damit Scotty!

You know the Prime Directive specifically prohibits passing advanced
technology to primitive cultures!!
