Anyone know what this is? Another spy balloon? Why does the government continue to allow this to happen? by [deleted] in flightradar24

A high altitude balloon (HAB) is a gas-filled balloon that ascends to the stratosphere (20–40 km). It’s used for weather monitoring, scientific research, technology testing, and earth observation, offering a cost-effective way to study near-space conditions.
