This Blimp isn’t doing Research!!
The U.S. Navy research laboratory says the blimp is a government research airship conducting aerial mapping, and that the MZ-3A lighter than air blimp began roaming above the D.C. area on September 21 and can remain stationary for more than 12 hours.
The blimp is mapping in the flight restriction zones around Washington D.C. It includes places like the Department of Agriculture and at some of our major airports like BWI.
