More comes to mind.
During the Trans Pacific with Per Lindstrand/Branson an incident ocurred during a gas bottle drop when the capsule was thrown off centre. Later in the flight a 747 passed within about 3 miles when it re-routed to see the balloon. The cameras on the capsules had fixed lenses [no zoom] but were steerable from inside the capsule by a pan/tilt head.
In some of the later flights we used a number of executive jets as chase planes to RV with the balloons and it was part of the routine to try and get shots of ourselves from the capsule cameras.
I was around as part of the TV crew for most of the past 25 years of ballooning records and designed the onboard camera systems.
This subject will bore everyone rigid. Mail me if you want more info.
