S-58 Start-up, Take-Off and Departure (Turn up audio).

Disclaimer: For those that LOVEEEEE the sound of turbine engines, this video is for you..... View in Landscape..
Prior to 2022, I'd never heard nor seen Aerial Lift Operations. It's an amazing part of Rotary Wing Operations. FAR Part 133. This departing S-58 is leaving for an HVAC mission to lift 20 Roof Top Untis for a school in Houston, TX.
Enjoy.
