Jun 29 2009Boom Boom: Guy Snaps Supersonic Picture

Ronald Dejarnett is the U.S. Navy sonar technician that snapped this pic of an F-22 going boom boom over the Gulf of Alaska. Quick shootin', Ronald -- I probably would have peed a little and yelled DECEPTICON! But that could be my special forces training talking.

my grandma can walk faster than that. kinda... a little... no i lied. a lot.... she cant even speak english... or spanish... maybe because shes vietnamese... i need a drink.
10. scurl - June 29, 2009 5:38 PM
this reminds me, i need to get my car's emissions tested. also...crop dusting.
11. Mary-Jane - June 29, 2009 5:44 PM
Woah....
12. Ollie Williams - June 29, 2009 5:44 PM
I just crop dusted the entire office.

FAKE!!!!
This is a complete photoshop job. You can tell uitts a fake because the shadow's are all wrong.
This is exactly like that scene in the movie Never Back Down where Max went to america to try and set a world speed motorcycle record on a bike he made in australia. The speed made him turn into a cannibal.
15. Ollie Williams - June 29, 2009 5:48 PM
From source that made me lol for rizzle:

16. Billy Rapture - June 29, 2009 5:56 PM
@15
There are no shadows.
Why does everyone say the shadows are all wrong?
Think before you speak.
17. ikiness - June 29, 2009 5:57 PM
@16 Ahahahaaa it does.
Also, the mention of 'decepticon' made me jizz in my face.
18. STOMPY - June 29, 2009 5:58 PM
WHY DO PEOPLE THINK THE SHADOWS ARE ALL WRONG AND WHAT IS WITH THIS NEVER BACK DOWN CRAP, I'VE HAD IT UP TO HERE WITH THIS, THIS MAKES ME SO MAD! I AM GOING TO GO HOME CRYING NOW.
freakin n00bs
19. ikiness - June 29, 2009 5:58 PM
@17 You're new to Geekologie, right?
20. naas - June 29, 2009 5:59 PM
@17 right!? I was thinking the same thing! This is completely accurate, I think that person is blind or something, zomg. I also don't remember any F-22s in the hit movie Never Back Down but I had 3 bathroom breaks so I may have missed it
21. Flyboy - June 29, 2009 6:04 PM
This is a great picture!!!!

No, ive been viewing this site for a long time.
Are you?
24. ikiness - June 29, 2009 6:12 PM
@Billy Rapture
Nope. You just missed the Daisy thing. Daisy posts the same comment about shadows on (almost) every post. Like the Geekologie mascot.
25. freddy k - June 29, 2009 6:14 PM
#24 if you have been viewing this for a while, then you know this is Daisy's thing. Albeit, sometimes a little annoying, but its why we love her. Actually I think I like her because of the reaction of noobs.
26. Pat - June 29, 2009 6:25 PM
Awesome shot. I wonder what ISO he was using to capture this.
27. Grog - June 29, 2009 6:26 PM
@19 was gona say the same thing.
28. Ron - June 29, 2009 6:33 PM
This is a pretty sweet shot, but with many shots like these, you cant actually know if its before, during, or after actually breaking the sound barrier, unless you are there.
The cloud is quickly formed because of such a high drag from it moving so fast.
More details at http://www.wired.com/dangerroom/2007/04/picture_this_tr/
The clouds last as long as the air is there, so capturing such an event is not as impressive as the fact that he was as close as he was to take the shot.

OMG! he just opened a portal to the underworld! We're Doom >.<
30. Lissy - June 29, 2009 8:13 PM
@10
its alright my grandma doesnt speak at all just mummbles..
31. Lissy - June 29, 2009 8:20 PM
@ 17 & 21
yall are noobs. daisy posts the same thing up every blog doesnt matter if there are shadows are not. arguing wont do anything. youll see her under every blog even more than once some times.
32. hey HEY - June 29, 2009 8:26 PM
hot damn! that's insane!
33. Bird - June 29, 2009 8:42 PM
OMG, this is freaking sweet
Also, I work on this jet, so it's awesome for me to actually be able to see this
b/c it don't happen often
34. Topher - June 29, 2009 11:18 PM
@25 I'm liking where this is going...
35. Jarch - June 29, 2009 11:55 PM
@29: Don't be stupid, this is not the "sound barrier" breaking. In all likeliness the Raptor was merely going transonic, not supersonic. It is not about the drag from speed (Note: hypersonic craft do not experience PGS formations, despite being much faster, whereas some subsonic craft can cause it under very specific conditions), but rather it is due to a large pressure drop near the tail of the craft.
You were right about it being a cloud though. It's condensed water vapor because of the pressure, even though the temperature does not differ.
The two wing-tip tails are an unrelated occurrence, but due to relatively the same pressure drop.
@35: Any carrier based launch of an F-18 or F-22 should net this effect every once in a while. The high humidity helps since they won't hit Mach1 very close to the carrier.
36. Jaded Icon - June 30, 2009 7:10 AM
@ 7 & 8
You are both correct!

Damn right she is, she fished out quite a few these days. hahahaha.
and as for the shot,
OH MY F**KING GOD.

@33 So wait...... it's fake then? I am so confused & haven't been here too long

naas - You don't sound irate or arrogant enough! For goodness sakes, your speling and grammar are too accurate as well. You are not a great n00b impersonator...
41. Vegas - June 30, 2009 10:37 AM
@29/37--this is an F-22 in a transonic state. Transonic is an aeronautics term referring to the condition in which a range of velocities of airflow exist surrounding and flowing past an airplane. Air flow velocities are concurrently below, at, and above the speed of sound at the pressure and temperature of the airflow of the air vehicle's local environment, (this all depends on altitude and relative humidity. In a dry climate, the chance of being able to take a photograph like this would be slim. The speed of sound also varies depending on the altitude and current weather conditions). It is formally defined as the range of speeds between the critical mach number, when some parts of the airflow over an air vehicle or air foil are supersonic, and a higher speed, typically near Mach 1.2, when all of the airflow is supersonic. Between these speeds some of the airflow is supersonic, and some is not. So it is possible that this aircraft created a 'sonicboom' at the same time water molecules around the aircraft were being vaporized do to the aircrafts drag, resulting in friction, through the air. However, the picture above is not technically created by a 'sonicboom' clear as mud? thought so...

@42 cold & cruel
43. B - June 30, 2009 11:41 AM
@37
Spot on, man. I was going to post pretty much exactly what you said, but you saved me the trouble.
The pressure drop that causes the condensation is often associated with an oblique shock where the flow around the airplane reaches mach 1, but that does not = sonic boom.
44. naas - June 30, 2009 12:11 PM
Well thank you professor pickypants for absolute clarification with your associate mr. analretentively-unhappy....... because all of us here are training to become air born pilots and anything less that absolute accuracy is intolerable.
Let's see if we can't find something else wrong with the interwebz now to start several other paragraph long arguments showing the world how wrong it is
45. captain obvious - June 30, 2009 2:17 PM
i love when the post about daisy go on and on and on and on and on......
i forsee in the future one day, that everyone will have seen NEVER BACK DOWN who reads Geekologie post and totally agree....EVERY PICTURE ON THIS SITE IS PHOTO SHOPPED!
46. scurl - June 30, 2009 2:32 PM
i have to admit to checking the imdb listing for never back down....but i still don't think i'll watch it because it looks so stupid. and this is coming from a guy who sat through the movie druids. twice. and i've watched troll 2 four times. nilbog HA
but i sure do heart daisy most days.
47. naas - June 30, 2009 2:39 PM
I haven't seen never back down either, but I know the whole movie from start to finish thanks to all of Daisys references to it

Prandtl- Glauert singularity
49. Rhialto - July 1, 2009 8:23 AM
What you see here is probably the condensation cloud around the shockwave.
50. Iron-Balls McGinty - July 1, 2009 9:25 AM
Any nerd and cut and paste internet articles about sonic booms, and con-trails..Although, I make my own sonic booms in my bathroom toilet after reading this crap and eating a bowl of wendy's chili.
