Didn’t they have transparent aluminum in a Star Trek movie? I bet it would be lightweight.
We are getting there:
Yes they did. They were returning a Blue wale to Earth to reseed our depleted oceans. The crew had landed in Golden Gate Park and the shore party had left a Klingon battle cruiser parked there with the cloaking device left fully engaged. As they left Scotty made a comment to remember where they had parked. (Best line in the whole episode!)
(Second best had Commander Scot talking to a mouse attached to a contemporary Desk top computer. When shown the actual way to enter commands, his comment was 'How Quaint')
