573 kts is roughly the SOUND BARRIER at those altitudes
It’s the sound barrier if 644 would have been airspeed, but 644 is groundspeed in this case.

Uhhhh. Close but that’s ground speed not true airspeed. Mach 1.00 is a TAS value not a GS one. Things like altitude, temperature, and air pressure affect Mach 1.00. These are also the same factors that determine True Air Speed. (Including Calibrated Air Speed, CAS. That’s indicated airspeed corrected for installational errors.) GS is determined by which direction thewind is blowing from and how fast it is. I remember a thread talked about this. It was pretty detailed.
BTW:The fastest the Citation X flew was Mach 0.99 in test flights. Some of the parts of the airplane travel in excess of Mach 1 when the A/C is at M 0.99 though.

Close, but about 2 hours and 14 minutes too late
For a light jet similar to a small Citation, the SJ30 is smokin’ fast with long legs!
But better explained.

Not really, don’t forget we’re talking about groundspeeds here. A balloon blown by a 600kt wind would experience the same effect.
That’s supersonic!

That’s 18 hours and 32 minutes late. But thanks for the balloon. Is it red?
Sorry, read the last post in the last page. Didn’t see that it continued!
I LIKE BALLOONS.
I saw this one balloon that was flying past my house at a rate a heli would have a hard time keeping up with (about 30 kts). It was at about 200-300 ft AGL.
I’ve seen balloons on numerous occasions while flying, most below 10,000 but i’ve seen one (or a bunch or 2-3) above 12,000.
I never told you guys about the time I hit a kite.
That’s another story. Gotta go flying.
What kind of peice of crap helicopter can’t fly at 30 knots? (especially when there is apparently 30kts of wind!)
Dean Kamen, creator of the Segway Human Transporter (among many other things, like the first insulin pumps for diabetics) owns this Premier 1, based at MHT.
The world headquarters for Segway (and DEKA) is a quarter mile from my apartment and his mansion is nearby. (you can look it up on Google Earth)
He’s not a very good pilot: NTSB report

Is this the Packers charter?
Yes, but why were they in San Francisco?

My guess would be TO PLAY A FOOTBALL GAME???
That’s like asking why a car is on a road…
Just messin with ya!
To beat, much to the delight of my girlfriend so she could rub it in to her son, the 49ers. (Me? I don’t give a damn - or even a darn - about football.)
“NTSB report” linky no worky.
All I can find on N16DK is a fatal crash of an RV-6
THREAD HIJACK, I like this hostess chick, let’s call her Lisa(because that’s her name,) that works at Chile’s and she’s friends w/ one of my friends, but he’s not really helping me get hooked up w/ her. I eat at Chile’s somewhat regularly, what should I say to her? I know this is an aviation thread but I’m drowning here, I need metaphorical cpr w/ this chick so I don’t metaphorcally die.
I believe I got all of the english correct for dami on this one.
Let’s take this back to aviation, she has the curves of a Falcon 2000 with the speed of a Citation X. (And by that I mean she’s perky w/ rather smooth lines… if you know what I mean)
Disclaimer: I appologize in advance if I offended anybody by this post.
Please submit all releationship how tos and “what should I do” questions to Jenn Sterger at CNNSI.com.
- It’s Chili’s
- Your friend isn’t helping you because he’s trying to hook up with her too.
- Say whatever you want to her or start by just talking to her but whatever you do, don’t tell her she looks like an airplane.
- Call Dr. Laura, Dr. Phil or read that mars/venus book.
- Are we in junior high school?
