The US Government site **broken link removed** has all sorts of free doucments and handbooks. You will have to register and show a need for the documents. I am not sure how they decide who to give a registration number to, but if you are working on a military project they will.
Just go to **broken link removed**
and do search, you will find all current us military handbook and standard.
Not need to register.
But sorry no mil-hdbk-217e, only have mil-hdbk-217f.
