The Pentagon has suspended the JLENS program at Aberdeen Proving Ground pending the outcome of an investigation into last week's runaway blimp, according to the L.A. Times.

The blimp that escaped its mooring at Aberdeen Proving Ground on Oct. 28 was one of a pair deployed to protect an area from North Carolina to Boston. Together the blimps formed a program called JLENS—Joint Land Attack Cruise Missile Defense Netted Sensor System—intended to protect the region from objects like missiles, ground targets, swarming boats and unmanned aircraft.

The North American Aerospace Defense Command was conducting the three-year test, in which two blimps watched the region from 9,950 feet in the air, to see how the JLENS technology could fit in with existing defense systems. Now the Pentagon has suspended the JLENS program indefinitely, the L.A. Times reports.

In addition, citizens and lawmakers are calling for a review of JLENS after the runaway blimp broke away from its mooring in Harford County and dragged its tether from Maryland to northeast Pennsylvania, knocking out power for approximately 30,000 people along the way. While the Army was quick to say that there was no loss of life, lawmakers are questioning whether the program is worth the risk.

The blimp that escaped from Aberdeen "endangered lives, disrupted paths, left thousands of people without electricity" and raises the question of the value of JLENS, Rep. Elijah Cummings (D-Md.) told WJZ.

Police had to shoot down part of the blimp, technically called an aerostat, in a difficult-to-access ravine, defense officials said, because it had not completely deflated, despite its manufacturer's claim that it had self-deflating safety mechanisms built in.
