DEFCON 23 Badge Challenge

I'm confused by the "WFST HDXE HGY BNK BAWH QJG PSOR WNFATG IDDW OQUHVNKINGCY GQG CTUK." vigenere cipher.

if decoded with "LASTORY", i get "lfaatmzthofnwmqaeocsieswyiwhptoppmydqcohwmxnojkpsvcbbw."

how did they come up with "WELL DONE GET THE BLUE KEY PASS PHRASE FROM OPPENHEIMERS BIG BANG."

Try http://rumkin.com/tools/cipher/vigenere-keyed.php and enter LASTORY as both alphabet key and passphrase!

using "LASTORYBCDEFGHIJKMNPQUVWXZ" as alphabet yields "xkaajeskmkddnkhavkqkgtbcctnfbcklferettksnkorkfchomhbsm."
