Keith's note: I learned last night that David Webb has died. I first met David 30 years ago when I was just entering the space business. He was always willing to offer advice, a spare bedroom when I visited DC, and offer introductions to people in the business. I was not alone in receiving his mentorship. Indeed, over the years, I suspect that everyone in the space community benefited from his interests and activities. A look at his Wikipedia entry may seem voluminous but it is woefully incomplete. He was a gentle soul. Ad Astra.
