The various crafts and their flight/performance capabilities? (Black triangle, saucer, tic tac)

Anyone have information on the various models of craft (whether it be alien or human reverse engineered)? Black triangle, saucer, tic tac.

I’m referring to their performance/flight capabilities, material composition, propulsion system, etc.

Supposedly the reptilians/Nordics use the black triangle, greys use the saucers, and the tic tacs I haven’t read any specific species using that craft.
