Every once in awhile I get a curious passenger come up to cockpit with anxiety & start asking questions that they fear the most. I don't mind these questions because it helps to reduce the anxiety when you have clear simple explanations about myths. Once such myth is what if you lose both engines in flight? Will the airplane just drop out of the sky? Anyone who understands basic aerodynamics will appreciate the fact that a wing on an airplane acts like a glider when you lose both engines. The airplane will still fly. A pilot will maintain a minimum glide speed to stretch the glide out into they can reach an airport. This is called a dead stick landing & has been made successful by pilots in the past. In the mid-90' a Canadian Airbus Airliner made a dead stick landing on a tiny island over the North Atlantic after losing both it's engines in cruise flight.  All the passengers walked away safely. Another myth is can traditional convective turbulence cause an airplane to crash. Of course this is no. Convective turbulence is when the sun's radiation rays heats the earth's surface causing up drafts & down drafts which is the turbulence that most airliners fly through. Convective turbulence may make you fell uncomfortable, but is quite harmless. Finally, people wonder about mid air collisions. The chance of a mid air collision is very remote. The chances are greater that a earthquake will kill you before a mid air collision. The chances of a mid air collision was further reduce by new innovative technology like the TCAS, or Traffic Collision Avoidance System that was invented in the early 90's. The TCAS is in every airline cockpit, & corporate jet. It's a tiny computer that monitors any aircraft threat that gets too close & commuicates with that other aircraft telling it to go one way while the other aircraft goes the other. In my opinion that was one of the best safety devices in the last 50 years.
