Lightning strikes on airplanes are not rare, and usually do not have a serious impact. An airplane is designed to withstand a powerful bolt of lightning without compromising the safety of the people inside. However, it is still important to take proper precautions to avoid flying into ...
but sometimes pilots have to fly through a thunderstorm, which also increases the risk of a possible lightning strike. Thunderclouds can appear in altitudes between one and over ten kilometres. Most often lightning strikes occur during takeoff or before landing when the aircraft is...
