>Dear Readers:

>Several readers kindly sent me corrections regarding the landing pad used
>in the first DC-XA flight, as mentioned in Space Access Update no. 64.
>(That update stated that DC-XA was still landing on a concrete slab, which
>was incorrect. See the final item in this message for Henry Vanderbilt's
>correction.) While I appreciated the excellent information several people
>provided, there seemed to be a common misconception that *I* was the author
>of the Space Access Update. Since this misunderstanding has cropped-up
>before, I'd like to make sure everyone understands that I am *not* the
>author of the vast majority of the material distributed on this mailing
>list and stored on the archive. That's why the attribution for the items
>redistributed on this list is *always* preserved at beginning of each item.
>So, check those attributions when responding, or the actual author probably
>won't get your message. (Please feel free to co-copy me on such messages,
>of course.)
>
>I wish I had the kind of information to pass along that people like Henry
>do, but that's not the case. As such my role in SSRT/SSTO/X-33 advocacy for
>the last 3.5 years has merely been to collect the best information I can
>find from people like Henry Vanderbilt & the Space Access Society, Henry
>Spencer, Allen Sherzer, etc., store it all in the FTP/Web archive, and
>relay it to people via this mailing list.
>
>Having said all that, I'd like to add that if any readers want to send me
>information (whether it be news, corrections, etc.) for possible inclusion
>in the archive and relay to this list, I'd be happy to receive it. Make
>sure you explicity state that I can pass along the information you've
>provided, and if you'd prefer to remain anonymous, state that as well so
>I'll know to remove all references to the source of the information. (BTW,
>please suggest an attribution for the material like "sources close to the
>program", "knowledgeable sources", etc.) As mentioned earlier, I received
>some excellent information as corrections to SAU 64, but I couldn't pass it
>along becase I was unable to get the actual sources to consent to its
>redistribution.
