A newly released report details the damage caused by a December 2017 World View hydrogen balloon explosion.
The report contains photos of the aftermath, including cracked windows and blown-in walls at the World View facility. It also contains an extensive list of all the damage.
That facility is owned by the county, and leased by the company.
The report was prepared after Pima County Supervisor Ally Miller called for a vote on whether there should be a county investigation into the explosion.
"It is a miracle that no one was seriously injured or killed by this violent explosion,” she wrote in the memo. “It could have been far worse."
The damages cost the county $200,000, which was covered by insurance.
The company has launched an independent investigation into the explosion, and has suspended use of hydrogen on the launch pad as that investigation continues.
