There is a problem with intrapage consistency. At the top of the page, the limit of 100km for "space" is attributed to the FAI whereas at the bottom of the page it is attributed to the FAA. Someone needs to sort this out?

Also, the top of the page say 13 flights have made it over 50 miles, but the bottom says 12. Jwolfe 08:11, 3 Jul 2004 (UTC) (the above comment is not mine, just this one).

[edit] Mach # on first flight

There's an error of fact in the last change, about the X-15's first flight making Scott Crossfield the first to go supersonic in a glider. The first flight only had a top speed of Mach 0.79.

However, the Southern California Soaring Society (might have been Association instead of Society) did award a trophy to Crossfield for the fastest glide to a landing from 38,000 feet on that flight. The trophy was a nicely finished and mounted streamlined brick.

Perhaps the author of this note would like to update it.

Another possible notation would be that this was one of only two X-15 flights whose top speed was subsonic. The other was an emergency landing by Forrest Petersen when the engine didn't light -- even then he got to Mach 0.97, almost supersonic in a pure glide. On all other flights the X-15 operated as a motorglider, so it's still fair to say that it was the fastest glider on record until the Space Shuttle's first reentry.

Actually this note is partly a familiarization exercise, I just registered and am checking out details in Wikipedia. That explains some of the text oddities in this note.

[edit] Measurement Units

I only see the speed and altitude listed in Metric in the Record Flights and Pilots sections. I know that most of the world uses the Metric system, but since this is an American aircraft, it stands to reason that the performance is listed in our units, too. TwinTurboZ 05:07, 8 February 2007 (UTC)

[edit] Adding Links

After seeing pages from the Aviation Trivia web site linked to from Wikipedia articles, it seemed appropriate to ad a link to pages that have much more comprehensive statistics regarding the aircraft and a wav file of how it sounds. That was the reasoning for the single link I added to the one page. The other links were added by others. The link already on the page: Another link to an unofficial X-15 web site appears to be inoperative. Perhaps it should be removed. --Crvarvaro 08:03, 5 March 2007 (UTC)crvarvaro
