While the wind was a factor in Tom Cruise's self-completed stunt on the Burj Kalifah (though less of a problem than the massive force Cruise faced when he did a stunt hanging from a cargo plane in the next M:I film), the sequence used cables that were so strong and numerous (edited out of the shot with CGI) that the only way Cruise would have been endangered would have been having a plane slam into the building during filming.
