SR-71 Blackbird
Thanks for your note on my talk page regarding the SR-71, and welcome to wikipedia! I did indeed find your account very informative, and it's fantastic that there's a former SR-71 pilot on wikipedia now. I think Egan Loo was a bit too quick to remove your contribution, but I did a quick bit of internet research to corroborate it and readded the info to the SR-71 page. I'll be watching it closely for further developments.

On another note, you may want to use a signature to sign your talk-page edits in the future. Simply typing ~ will automatically generate a link back to your user and talk pages and a date/time stamp. If you'd like to change the default signature, you can do so using the preferences button at the top-right of your screen when logged in (see more here: Sign your posts on talk pages). In any case, you've made a great start - the key to being successful here is not being afraid to make mistakes (other people will fix them) and being willing to talk issues out on the talk pages. I'm looking forward to seeing more of your contributions. -Lommer | talk 19:22, 15 September 2005 (UTC)

Signing articles
Hi David,

I removed your signature from the SR-71 article. It is actually official policy that signatures do not belong in an article. The text, from that reference, is Don't "sign" edits you make to regular articles (the software keeps track of who makes every change). I've actually been watching the SR-71 article evolve and I'm thankful for your contributions. That aircraft has been a personal favorite of mine for a very long time =). Thanks for helping us out here. Triddle 07:05, 19 September 2005 (UTC)

Please do not revert the SR-71 article again
Hi David, please do not revert the SR-71 article again. It is policy that user signatures do not belong in the article. Please take a look at the article and think about how much that signature interrupts the style of the article. It also makes it unique among every other Wikipedia article. It is not in the spirit of Wikipedia to put personal gratification above the quality of the work we produce here. Please understand that we do like to have fun and we very much notice good contributions but we do those things all outside of the main articles in the talk page. Please also understand that if you continue to replace your user signature in the SR-71 article that penalties can be applied, such as blocking. I will remove your signature from the article myself; again, please, do not re-add it. Triddle 07:25, 19 September 2005 (UTC)

Sorry David, I misread my watchlist and failed to verify a change to the article had been made. I thought you had replaced your signature again but after double checking it seems no such thing has happened. Again, I am deeply sorry for the mistake. Triddle 07:29, 19 September 2005 (UTC)

Surveillance aircraft page
Mr. Dempster, could you perhaps look over the article on surveillance aircraft and see if you've got any comments?

It's fantastic to have somebody with first-hand experience on these amazing machines contributing to the Wikipedia. --Robert Merkel 06:06, 22 September 2005 (UTC)

Greetings!
Well well my friend, it was good to hear from you. I remain surprised that all those stories I read about the SR-71's and astronaut wings were in fact not true! But I defer to your wisdom. I would be remiss if I didn't mention that I worshipped all of y'all during my intensely curious childhood (F-16s, SR-71s and the ill-fated F-20 Tigershark took most of my attention). I even went so far as to procure Habu patches for my leather jacket; I was the envy of my intermediate school sporting that sleek silhouette. ;) Peace to you, and if you ever feel like trading beer let me know; I have a stash like you wouldn't believe. &middot; Katefan0(scribble) 01:43, 30 September 2005 (UTC)

FICON
Thank you for the nice message David. I'm actually the restorations crew chief for one of the surviving RF-84Ks (52-7266) so every bit of history is doubly interesting. Do you by chance know anyone from 91st SRS who flew the FICON 84s? We've uncovered some markings on the aircraft that do not appear in the (scarce) USAF photos and have been having a heck of a hard time finding any information about them. I also have the pleasure of working in the imposing shadow of the B-1A number 3 as I humbly scrub away at the Thunderstreak.

Interesting comment about SR-71 top speed. The Mach number and the corresponding IAS for any given altitude should match unless one of the numbers is IAS and the other TAS or the atmospheric conditions (air density) was not "standard" (more likely IMHO). - Emt147 Burninate!  07:20, 8 May 2006 (UTC)

SR-71
Thanks for the comment on the reversion. BTW...are you local in the AV? I'd like to find out more info about the SRs that were stored for a time up at Mojave (where I work). I have some old photos given to me by a friend, but little explanation about why they were stored there, and where they went. Akradecki 03:36, 9 April 2007 (UTC)
 * Hi David, pics of the Mojave blackbirds have just been emailed over to you.... thanks for looking into this! Akradecki 04:44, 19 April 2007 (UTC)

Fuel PF-1
Hello David. Searching for information about the fuel of the SR-71 and its predecessors you'll always find JP-7. But several sources claim that the first special fuel for the SR-71/J58 was called PF-1. JP-7 replaced it in the early 1970s. While some sources say PF-1 was simply renamed to JP-7 others state that JP-7 is different, developed by Shell for the YF-12A and less aggressive than PF-1 so that the already existing KC-135Q were modified with less sophisticated fuel lines and bladders (Robert S. Hopkins' book on KC-135). Furthermore, later the designation PF-1 has been used for a priming fluid for cruise missile engines (MIL-DTL-87173). Could you as experienced Blackbird-witness tell me something about the PF-1? Thank you in advance. --80.137.18.96 14:35, 20 April 2007 (UTC) (de:Benutzer:Arcturus)
 * Thanks for your reply. No need to hurry, I'll keep watching your talk page and the SR-71 article for news on this topic. --80.137.43.149 12:55, 2 May 2007 (UTC) (de:Benutzer:Arcturus)
 * Thank you very much for your investigation. Not the answer I expected (or at least hoped for) but thats secondary since we should be committed to truth, not to expectations or interesting stories. I'll try to find out something more on this . --80.137.59.87 08:48, 24 June 2007 (UTC) (de:Benutzer:Arcturus)

SR-71
David, Originally the article stated 12 were lost or destroyed. There have been numerous changes though. Now the artical states 13 in one section and 12 in another. There is also alot of changes with respect to lost aircraft and destroyed aircraft. Possibly 12 of them were destroyed and the 13th was lost. This should be clarified 68.244.13.195 23:27, 6 August 2007 (UTC)

TEST
This is a practice test of adding and/or deleting items from my talk page.

Just a little something you might like to see

Simulator
Didn't see that on the main SR-71 page. Feel free to repost it and I will see if I can get some sources to back it up. BTW, thanks for your service (I was a B-52H EWO myself). Buffs (talk) 23:25, 12 March 2012 (UTC)

B47 1961 Crash in Wichita, Kansas
I am trying to reconnect with people from my past. Are you the David Dempster that was in the Air Force with my dad, Capt. Byron V. Foster? — Preceding unsigned comment added by Peggymatt (talk • contribs) 04:14, 31 July 2013 (UTC)
