The incident happened on Tuesday, between Marfa and Valentine.
High winds reportedly brought down the 210' x 70' foot radar balloon, which is connected to a tether.
No one was hurt in the incident. The crash caused more than $2 million in damage.
The unmanned blimp has been floating about 12,000 feet above the ground for more than 15 years.
