First, I want to say that I appreciate the fact that so many of you took the time to post your questions. Reading them shows me what you care about in terms of transportation. So, thank you for contributing to this useful exchange.
I also have to say that I enjoyed answering your questions. Being able to communicate directly to you is an important opportunity, important enough that I want to continue taking your questions--and answering them.
So, we'll keep the lines open, you keep those questions coming, and I'll have another installment of "On The Go" in a few weeks. Remember you can post your questions on the "Discussions" tab on my Facebook page, using the #q4ray hashtag on Twitter, or through the "Comments" feature on this blog.
Finally, to @lexalexander on Twitter, who asked, "Where are the jet packs; they said there'd be jet packs?" I can only say that I share your disappointment that the 21st century so far lacks a decent jet pack. But it may be of some consolation that, at last year's Oshkosh AirVenture, I did see a flying car.
And if jet packs aren't just around the corner, there are plenty of innovations on their way to help get people and goods where they need to go.
Thanks for tuning in.
