This mod adds a parachute box with 5 parachutes and and an ejection seat to leave planes (and rockets) in unlucky situations.
Just unzip into your game folder. Make sure that you have my plugin installed too, download it at http://kerbalspaceport.com/vanguard-technologies-plugin/
How to use
To get a chute from the parachute box, come closer than 1m to it on EVA and right-click it.
The ejection seat is triggered using action groups, by default it uses the abort one.
In both cases, you can deploy the parachute either with a right-click on the Kerbal or by pressing jump and use at the same time (space+f by default, this also deploys the parachute of all Kerbals in range).
There are two modes now, semi and full, but there's no big difference between them on Kerbin, but maybe on planets with a sparse atmosphere, I don't know.
