The Mil Mi-54 was a projected twin-turbine civil utility helicopter, first announced in 1992, intended to replace the Mi-2 and the Mi-8 helicopters. It was planned to use two 574 kW Saturn/Lyulka AL-32 turboshaft engines, four-bladed main and tail rotors, and fixed tricycle-type landing gear with one nosewheel and two rear wheels on sponsons.

gollark: Other OSes can just ignore the permissions, is the thing.
gollark: The designers obviously did not want unprivileged users to be able to arbitrarily make themselves have permissions.
gollark: I doubt it's possible from within MacOS for obvious security reasons, but if you can boot into a Linux USB stick or something you can edit it from there.
gollark: There are even tons of copies on github, including one memorably added to the repository of DMCAs via a bug they won't patch.
