Away 48 made an appearance in the cameras of Away 49. They were a few miles apart when the faster climbing Away 49 overtook Away 48. Away 48 shows up about six times in each of Away 49′s five cameras. We can tell it’s Away 48 from top to bottom travel through the course of the images, and the fact the appearance coincides with the altitude of the rendezvous. The balloon is about 54 feet in diameter at this level.
I can think of no other private company that has ever launched two missions to the edge of space at the same time.
It occurs to me that on missions where you launch a rocket from a balloon, having a second balloon filming the launch could help to analyze any problems that occur.
