I'm sure this will be helpful for airplanes. Thanks for fixing it up for 1.2!
Is the short delay after the kerbal appears at the hatch and them rocketing away intentional? Could that be reduced?
Also, you might consider adding an ejection sound and/or rocket effect. Here are two youtube videos for reference material, one with sound and the other showing a short clip from Gemini testing.
Edit: Hrm, when launch clamped on the pad there is no delay.
Edit 2: Another idea: add some divergence to the ejection trajectory so multiple kerbals don't make a perfect parachute tower. Also, is it impossible to make the ejection parts act as hatches where kerbals come out, to allow for multiple simultaneous ejections? I'm guessing you'd have to have the hatches built into the crew containing parts but I might as well ask!
