The TRUE Cause Will SHOCK You

Link for my Twin and Turbine Ice article: https://www.twinandturbine.com/impenitent-ice/ Every winter, pilots depart into snow and ice believing they are protected by modern deicing procedures. Most of the time they are—but not always. This video explores the science, history, and real-world limits of aviation deicing fluids, and how misunderstanding those limits can turn a routine winter takeoff into a fatal accident. Using the recent Challenger 650 crash in Bangor, Maine as a case study, we break down how deicing and anti-icing fluids work, what holdover times really mean, and why official weather reports can dangerously misrepresent actual snowfall intensity. From early days of scraping wings by hand, to the development of glycol-based Type I and Type IV fluids, to the hard-earned lessons of accidents like Air Florida Flight 90 and the LaGuardia Fokker 28 crash, winter operations have evolved through decades of tragedy and engineering. This video explains the difference between deicing and anti-icing, how fluid viscosity changes with temperature, why precipitation intensity matters more than most pilots realize, and what crews must do to ensure a clean wing before takeoff. We also discuss proper cold-weather takeoff technique, pretakeoff contamination checks, tactile inspections, and the critical mistakes that can occur when procedures are followed by the book but still misunderstood. If you are a pilot who flies in winter conditions, this is essential knowledge that could one day save your life. Understanding the limitations of holdover tables, the dangers of diluted fluids, and the need for cautious rotation technique can mean the difference between a normal flight and a catastrophic loss of control. Aviation safety is built on lessons written in ice and snow. This is one of them.
