EDIT: SORRY, LEARNER, YOUR AGARD AND RTO LINKS DO NOT SEEM TO WORK....
I am not sure about your problem.
I have just checked and I can download the files.
Can you open the links I posted?
Can you access these pages?
ftp://ftp.rta.nato.int/PubFullText/A...ARD-AG-300-14/
ftp://ftp.rta.nato.int/PubFullText/A.../AGARD-CP-519/
ftp://ftp.rta.nato.int/PubFulltext/A.../AGARD-CP-593/
What error message do you get?
If you can not access FTP servers, just let me know and we will arrange some other way.
