singapore, this particular route we are discussing and trying to navigate this thick of thunderstorm activity is nearly impossible. so chances are they encountered some rough weather. but we do know that the pilot did ask to ascend to 38,000 feet. and this is really crucial. because what we're talking about is the tops of thunderstorm clouds even on our satellite imagery, starting to reach the upper levels of our troposphere. we're talking about freezing temperatures. any kind of interaction with a thunderstorm at that high of an altitude we are talking about a possibility of ice, icing on the wings, icing on some of the crucial components on airplanes, including the pitot tube this is something that measures pressure and velocity of airplanes, and when ice interacts with this pitot tube basically, you lose your airspeed indicators and
