He's tens of thousands of feet from the ground and to view it from an angle would increase the distance from the camera by even more. Just hard to believe that there's cameras that can zoom that far. But I guess we have telescopes so no reason it's not possible. From the website: To achieve a live broadcast from 23 miles above the Earth, an optical ground tracking camera system was developed with features ranging from infrared to high-definition cameras. This system is called the "Joint Long-range Aerospace Imaging and Relay": JLAIR. Two JLAIR units are used for the Red Bull Stratos project. The JLAIR's primary imaging equipment includes: High-definition P2 camera (up to 60 frames per second) 4K (4,000 x 2,000-pixel) camera (up to 120 frames per second in 2K mode) Shortwave infrared camera Digital still camera The JLAIR Optical Tracking System offers capabilities not previously available to the private space industry or production companies: It carries a variety of high-power zoom lenses and large telescopes attached to an 8,000-pound motorized pedestal, previously used to track Space Shuttle launches. The control room allows technicians to select the best images available and transmit them in real time to Mission Control and/or broadcast viewers. JLAIR 1 is the first fully integrated tracking system on one vehicle chassis that includes an optics payload of over 1,000 pounds, an air-conditioned control room, an on-board generator for the tracker and sub-systems, and encoding and satellite transmission of HD video. JLAIR 2 shares the same features but employs a traditional trailer-mounted pedestal with separate control truck for mission flexibility. http://www.redbullstratos.com/technology/cameras-communications/ | ||

That's probably detrimental to his health ![]() I think you're underestimating the amounts of endurance the human body has at low temperatures. At -50 C, he should be able to survive for about fifteen minutes or so. But anyway, let's just watch ![]() On October 15 2012 02:00 Taekwon wrote: lol, falling even just a few hundred feet at that altitude will be enough to literally turn him into a cryogenic puppet I'm not so sure. Not to mention that they just said that the faceplate heating is just to prevent fogging and icing. | ||

Don't see a reason why it should raise if anything it should -> 0 as closer he gets to being in a vacuum But they are talking about the speed of sound on the earth under normal situations i assume | ||
