Mechjeb PANIC! mode?

[Capt. Hunt]

I noticed that if you open a mechjeb part in the action group editor there is a PANIC! command, what does it do?  I've tried activating it but I didn't see anything happen.

Did you find an answer?

It should cut trust, decouple to the last stage, try to turn the vessel up and then try to land.

I never knew this!

(Even though I just noticed this was a 2 year old necro....)

I believe it's a legacy function from before Action groups were a thing in KSP.  It served as an Abort button.  I believe Smart ASS is in the same boat, SAS controls back in the day only stopped rotation, you had no other options, SASS allowed you to aim at specific headings.
