[MM] Image Annotation editor's draft: shuttle vs rocket

Dave, 

 From last teleconf's minutes:

><dwood> Jacco, Please note that in Section 5.4, s/Apollo 7 Saturn
>shuttle launch/Apollo 7 Saturn rocket launch/
>  
>
I missed this during the teleconf, luckily my co-editors noticed and 
fixed this.

Thanks all for catching this,

Jacco
