Thank you, Mr. Chair.
Thanks to our witnesses for appearing here today.
This is a new and novel topic for me. I know virtually next to nothing in regard to airships, so I may ask some very basic questions to get them onto the record, both for my understanding and for that of anyone else who is reading this.
I'm getting some sense of it. Some of my questions may have been answered along the way, but how versatile is the current technology for airships? Are there weather restrictions? I don't know...do they run on any kinds of fuels at all? I don't understand the technology, so if you could walk us in a layman's way through the technology and its capabilities, that might give us some understanding of how it can be used.
