Use the -d flag with pkunzip, otherwise, you might end up with a big stinking mess.

Why was this not the default?

Probably because CP/M didn't have directories, and PKZIP had a definite familial relationship with LBR, which came from CP/M and therefore had no directories; and with ARC, which was cross-platform, including a CP/M port.

You're really going to watch 3d commercials?

While commercials do work, they rely on a tiny fraction of the viewing audience noticing what was advertised. Nobody is fascinated by commercials' content; nobody is going to keep their 3d glasses on when the commercials come on; and no advertiser is going to shoot 3d commercials. Except as a gimmick.

Doing other stuff during commercials is only sensible.

See this for a good explanation.

Delta-v from low earth orbit to the sun requires shedding 24km/s. Delta-v from earth orbit to pluto only requires 8.4km/s.

Actually you can get to the sun with far less -- something like 8.8km/s -- but it would take fantastically longer. In effect you would escape the entire solar system first, then kill your angular momentum completely.

Or you could take advantage of moon or other planet flybys, again reducing the energy required by trading it for massive amounts of time.

And incidentally, KSP cannot model quasisatellites, because the orbit is not just an ellipse -- it's an ellipse that shifts, due to gravitational effects from Earth and other bodies, after a given (large) number of orbits. KSP only uses true ellipses for planets and moons, and patched conics for ships and (maybe) asteroids. It doesn't use real 3-body mechanics at all.
