Man wins round of Scrabble-style gameshow with unusual word

Countdown is a long-running UK gameshow featuring various alpha-numerical challenges. One round gives constestants 30 seconds to figure out the longest word from a series of random letters drawn proportionately from rows of vowels and consonants. This results in annoyingly suggestive sets such as TINEYATPH, which seem to promise (but do not actually provide) full-length anagrams.

The longest word I could figure out was PATENT, but one of the contestants found a much better one.
