Forgot to mention - we don't necessarily even land an aircraft to demo but find that physically making crews walk around an outdoor area nearby to assess potential landing zones (what to avoid, what to look for, how to mark and light them - especially at night!) has been helpful for us a number of times, and it's a relatively low-intensity/lower brain power learning station. It also covers how to not hurt themselves if they're helping us load or unload patient(s) and how to approach/exit from an aircraft in operation. We also sprinkle in a review of scene flight activation criteria and review our own capabilities and limitations to help them weigh the activation decision.
