Aaron Jackson's charity Planting Peace last month launched an LGBT Pride flag into the stratosphere using a high-altitude balloon.

“On August 17, Planting Peace sent the first pride flag into space, and in doing so, declared space LGBTQ friendly,” the charity said in a press release.

The group launched the balloon outside of Milwaukee. A GoPro camera filmed as the flag ascended into the stratosphere for three hours before making its way back to Earth.

The flag reached an altitude of 21.1 miles, Planting Peace said.

“Our hope was to create the largest safe SPACE possible for our LGBTQ community,” the group said. “It also offered us a chance to reinforce, in a peaceful, beautiful way, our ongoing message to our LGBTQ family: You are loved, valued and beautiful.”

Planting Peace is best known for erecting Equality House, a rainbow-colored house located across from the Westboro Baptist Church, a Topeka, Kansas-based group opposed to LGBT rights.
