Cosmic Particles almost brings down plane

Crazily, who knew?, investigators are attempting to establish whether cosmic particles almost brought down a Qantas plane flying between Singapore and Perth. Here.

According to a previous article, what Qantas and the safety board are referring to as an "upset" actually involved:
"The jet, en route from Singapore to Perth, climbed 200ft upwards before returning to its cruising altitude of 37,000ft. About one minute later, it descended 650ft in the space of 20s - pitching downwards to a maximum of 8.4° - before regaining its cruise level once more.

Seventy seconds later it descended again, by 400ft in 16s, with nose-down pitch of 3.5°."

14 passengers were severely injured.
