What falls from the sky does not remain untouched. Within these files lie the schematics, reports, and research logs from projects designed to decode the unknowable. Each recovered craft is dismantled in theory and blueprint — its origins obscured, its purpose still debated. What is known: the technology is beyond us, yet the attempt to replicate it has already begun. Here you will find the timelines of these efforts: when the projects were initiated, the challenges that consumed them, the breakthroughs that reshaped them. To study these files is to glimpse the machinery of the impossible.
