Free eVTOL Corpus

A public-domain prior art commons covering eVTOL aircraft and eVTOL-adjacent flying machines — passenger air taxis, jetpacks, hover bikes, personal VTOL, tilt-rotor and tilt-wing demonstrators, military VTOL, ducted-fan and vectored-thrust craft, and the science fiction and academic literature that anticipated all of them.

The corpus IS the prior art commons. Every entry, at the moment of timestamped commit and quarterly release, is a defensive publication. There is no separate commons layer above this catalog — the structured data here, combined with the cryptographic timestamping in releases/, is itself the invalidity-contention material.
