KOS: Easy flight recorder script for your auto liftoff needs!.

[SpaceCarmelo]

Are you tired of writing on paper your flight data when testing a rocket, in order to write a kos program for auto-liftoff later? 

I was tired too! That's why i invented my own software.

Let me introduce you ACFEL! Automatic Check For Experimental Liftoff!

If you are a n00b like me, probably you used to build an experimental rocket, flight it to Kerbin orbit, write down on paper at what altitude you where pitching your nose, and then trying to reproduce your flight it with KOS with more or less Kerbal-Style results. 

But with this simple program you can finally take some snapshots of your liftoff in order to check your data later and write your liftoff program with no stress!

(edit: some stress included when you forget "." at the end of a line  )

Simply run ACFEL on your KOS CPU and spam Action Group 4 everytime you do something significant in your liftoff, ACFEL will print several .csv files containing altitude, apoapsis, throttle, pitch and all the informations you need when testing a rocket.

Then simply push your .csv on Github and make a Google Sheet document that takes data from the Github links (using the =IMPORTDATA("link") function on Google Sheets) and Hey! Look at that, that's your flight! Finally recorded. 

Hint#1: use ACFEL inside a folder since your .csv files will be exported in the same directory where the ACFEL.ks program is located! 

Hint#2: Google Sheets sometimes is buggy when gathering data from github, simply delete and paste the =IMPORTDATA function to make it update! 

Hint#3: Make graphics on Google Sheets and act like you're a NASA engineer!

TODO: Make an autopilot script that takes data from ACFEL!
