Not only blueprint drawings - this has actually been tested with the Saturn I booster: https://www.youtube.com/watch?...

| Soviet N-1 and Proton launchers had control units that could compensate for failed engines or short burns and still put the payload into its orbit.
Except that it never worked on the N-1 - all the launches resulted in catastrophic failures (http://en.wikipedia.org/wiki/N1_%28rocket%29)

You can import a Powerpoint or a PDF (there are more formats as well) and present on an iPad - everything you do gets recorded - then you can export to MP4 or YouTube. Obviously, you need to convince the lecturer to use it ;-) http://itunes.apple.com/us/app/explain-everything/id431493086?ls=1&mt=8 There are highlighters, a laser pointer - you can also save the whole lecture as a PDF (more or less - it takes screenshots of your slides).
