falling out of a plane

There's another you are in a spacesuit approach in a atmosphere free moon at a speed which is greater than the escape velocity to leave the moon's gravitational field. you have a portal gun what do you do?
 
Would not work due to horizontal velocity as you would have been traveling at the same speed as the plane.

120mph is I think is the terminal velocity of a human plus the speed that the plane was traveling on the horizontal plane. You could take into account of air resistance but at 5000ft you would hit the deck pretty quick.

You would be mash spuds. :D

Terminal velocity depends on the position of your body. ~120mph is the lowest it can be, but it can be much higher. Altitude also plays a big role because it very strongly affects the amount of air resistance, but in this example the altitude was stated to be 5000 feet so it wouldn't be relevant. From that altitude, I think terminal velocity would be in the range of ~120 to ~200.

The horizontal speed you being up is a good point, but not a dealbreaker. You'd no longer have any force pushing you horizontally, so if you repeated the process long enough air resistance would reduce your horizontal speed relative to the ground to zero.

A portal gun needs a surface to attach to so pointing it sideways wouldn’t work

How much of a surface? How about a cloud? Or any variation in the air? Moisture content, dust, pressure, movement...variation in any of those could be considered a surface in that it's a boundary between one thing and another.

Its not quiet right, you would be traveling along the horizontal axis at a minimum plane speed of 45mph then traveling down at about 120mph, which works out that you would hit the deck in about 30 seconds.

You would not be able to lose that much horizontal velocity in 30 seconds. You would bounce and be mash spuds. :D

Could you place the exit portal higher than the extrance portal and therefore stay up until you lost the horizontal velocity through air resistance? Drop to ~4900 feet, enter portal, exit portal at ~5000 feet, repeat until you've shed your horixontal velocity? I'm not clear on the fictional restrictions on this nonsensical technomagic :)

There would be no way to survive as there isn't any way to shed speed.

You could portal around until you reached ground at the same altitude. It was only 5000 feet, so you'd be able to breathe just fine. If you pick the right spot, you wouldn't even have to climb down.
 
as said, fire 2 portals at the ground and go up and down a few times to lose speed, but i'd probably get the angle slightly wrong and splat.
