On this episode of Aerospace Unplugged, we'll be talking to an orthopedic surgeon who found his way into aviation in the most unusual way. It's a fascinating story that was brought to light during the early stages of the pandemic, but the work of our guest, Dr. Arthur Kreitenberg dates back much further than that. Dr. K is the inventor of what is now called the Honeywell UV Treatment System. It's a device designed to roll up and down in an aircraft aisle and use UV light to treat surfaces on an airplane on the light that's emitted from that device is highly effective in eliminating pathogens and viruses. Dr. Kreitenberg, who is both an orthopedic surgeon and an engineer originally called this product, the Germ Falcon before his company Dimer, partnered up with Honeywell in 2020 to take his vision to a wider audience. This technology is now being used by airlines and aircraft operators around the world, but it was a heck of a journey for Arthur to get to this point.
