In more recent years, the airdock has been used for the construction of military blimps by Lockheed Martin. It has also been the subject of a number of conspiracy theories in recent years, since it is usually lit up every night, and its doors open and close at random times and are next to a rarely used runway that is well maintained for the little use it receives publicly.
