That's a pretty desperate article.
You're telling me two slightly tipsy men walked onto a plane with beer and caused - gasp - no trouble?
And there have been no bottle-equipped hijackers since September 11? Never!
As for "draining alcochol from a bottle and turning it into a molotov cocktail", well my Chemistry days are quite far behind me but I'd have to guess that seperating the alcohol from the rest of the liquid in a bottle would take a bunsen burner setup that would be difficult not to notice.
And sure, while we're at it, let's ban bottles, nailclippers, hairspray, cabin mirrors, sharp edges. Heck, just wrap the cabin in foam and have the passengers board the plane naked after a cavity search.
Alarmist reportage at its very worst.
