Anything looks good next to cars :-)

But yeah, flight is comparatively one of the safest ways to travel. But, in principle, it is still quite risky. A lot has to go right for an aircraft to successfully take off, fly, and land. Air speed must be maintained, the engines must remain mechanically sound, landing gear must be operating correctly, hydraulics on the wing and tail flaps must be operating, the pilot must be competent and alert. Countless systems must be working correctly. Any one of these things going wrong can result in mass casualties. Statistically our standards of operation are so high that flight is effectively safer than the automobile or trains or even lightning, as the article points out. But 1 in 12 million is still far from the effective 100% safety that Musk is promising for hyperloop.
