Correct. Of all the recent extreme sports feats out there, I suspect Felix Baumgartner's sky dive is the only thing that could have gotten approval from Muslim clerics. If he were Muslim, he could justify it by pointing out that he was helping develop better escape mechanisms for the residents of the International Space Station. The rest of the Extreme Sports community, however, would not.
A bit moot. Muslims at the time did not live near much timber resources.
