Not only do Drones provide amazing opportunities to capture images from places you never would have had access to previously. But they are also really fun to play around with. Yes, we've crashed a couple times, but when it comes to getting exterior angles for Real Estate, drones have become an integral tool.
I remember about 15 years ago, trying to get a quote from a helicoptor pilot to fly around an apartment community in a North Dallas suburb to capture a few random stills. It almost seems silly now that with a drone you can get amazing video and stills in a few minutes without paying someone to fly an aircraft in the sky.
