While his theory is being laboratory tested, he boards a plane to return to London, not realizng he is boarding a Reindeer within the allotted timeframe he predicted the plane would experience complete structural failure. Despite his theory is still unproven, Honey chooses to warn the passengers and crew of the potential disaster, causing a mid-air panic.
