Ahhh, nice warn evening, got the back door open, hear a jet....a JET...FedEx 727 to be exact. Nice to hear some real turbine noise once in awhile! Not these high-bypass turbofans! Anyway, I'll miss the stage 1 & 2 guys when they're gone. Or is FedEx gonna fly the 72s forever? I hear 2009 for us at UPS. Anyway, here's to real jet noise, the sound of freedom!

Aren't UPS 72s Tay-powered and, therefore, on the quiet end of things?
 
Tay powered

Yes, ours are Tay powered, "Quietfreighters" I miss the Concordes too, "Speedbird Concorde 2" climbing out of JFK...
 
We were on short final for 25L at LAS today when the Omega Tanker 707 began its takeoff roll on 25R. There was a bunch of black smoke then you could hear the roar of the mighty JT-3D's over our engine noise and our windscreen noise (minimal at 135 KIAS but still there). It looked like it finally struggled aloft at 10,000ft. or so down the runway then started a long slow climb to the southwest trailing smoke. It was a thing of beauty. I wish I was standing out by the runway so I could have taken it all in. As spectacular as the 707 was today, that paled in comparison to a fully loaded water assisted KC-135A takeoff.
 
I only saw the very end of the KC-135A and KC-135Q era (at Fairchild in early '95).

There were two (at least) on the ramp that had had the words "thrust" on the throttle quadrant changed to "noise" so that the verbage read "increase noise" instead of "increase thrust"

Hahaha..high-bypass turbofans do sound gay!!!

And I thought JT-8D's were high-bypass.
 
<3 high fuel burn and dirty burning :)


I heart trees.... but damn i love seein a lil trail of black exhaust behind jets... MMM LOVE THAT KEROSENE!!!
 
For current noisy takeoffs it would have to be the B-1B on afterburners. That thing shook my dishes a mile away when I lived on base.
 
If you're referring to noise, with no regards to actual thrust produced - the tweet would have to take the cake. 5 minutes next to a tweet without triple hearing protection would defean any individual and leave them screaming in agony. And those are old school turbojets, however wimpy as they may be.
 
Flew the Tweet...

So I know how loud that one is. And the B-1 on burner, night takeoff out of Diego, now that was LOUD! Someone told me the Vulcan was a loud plane, and the Russian Bear bomber (a prop).
 
The A-6 was and the EA-6B is loud. Must drive the hippies crazy in NW washington, with the Low levels thru the cascades.

NOSTALGIA ALERT: The sickest I have ever gotten was in the backseat of a prowler on a lowlevel up there as a mid during summer training. There we are flying thru the mountians and its all I can do to try to hit the little plastic bag.
 
Certainly not as loud as an F14 or F15 taking off but I was surprised how loud the F117 was starting its roll. But loudest non afterburner has to go to the AV8B Harrier. That thing was obnoxious on takeoff and landing.
 
Harrier

I think the AV-8 uses water injection, so that would explain the loudness. Once saw the NKC-135A takeoff, still heard it 20 minutes later climbing out on a still cool night.
 
I would have to say in full burner that the SR-71 was the loudest plane I ever heard! I saw one at an airshow years ago and it shook the ground along with me as it went by, very impressive! The B-1B is second in noise in full burner, another very impressive airplane!
 
How about being an RSU controller and having a 4 ship of T-38s taking off about 25 feet away from you. We couldn't hear a damn thing.

Speaking of how loud the Tweet was/is. At my AA physical, the flight doc looked at my hearing test results and said, "You must have been a Tweet IP." He showed me the printout and there is an entire frequency range that is completely gone in my right ear. Oh well, it was fun to fly upside down back in the day.
 
Actually the F-22's taking off in full AB are quite loud. Fought them a few times down at Tyndall and at Nellis.
 
I was between two roadblocks on the road that leads to the space shuttle launch pad back in 1985. I must have been within 1 mile of that thing blasting off. By far the loudest thing I ever heard. I also was holding short of 9L in SFB back in 1992 when a B-1B took off with full burner. The shuttle beat that hands down.

O.K. did I win the loudest aircraft/spaceship I ever heard contest going on here?
 
Dude, Pull my Finger......

Now dats loud! And kinda smells like kerosene or somma dat taco bell fuel!

AWWWW YEEEAAAAHHHH!!!​

The Tweet may not have been the loudest in terms of Decibels, but it sure led the pack in annoyance with that high-pitched whistle. Was it just as annoying from inside the cockpit?

The B-1 was loud for sure. It was even louder when you were standing 100' to the side of the runway (Oshkosh). It wasn't so much the sound as it was the physical buffeting from the sound waves! That was an astonishing experience.

The Vulcan has the same engines as the Concorde (Rolls-Royce Olympus), so I expect the noise level is about the same. There are groups in England who are trying to return examples of both aircraft to flight on the airshow circuit, which I expect will make the fuel companies very, very happy!

The Tu-95 Bear is supposedly the loudest aircraft in the world, since the tips of its 15,000 SHP counter-rotating propellers are trans-sonic. I'd like to hear one sometime to see just how bad it is.
The US also had an aircraft that had a similar noise level. Republic built a supersonic-blade turboprop version of its F-84 Thunderstreak fighter in an attempt to get the same speed with better fuel economy. The result was dubbed the XF-84H Thunderscreech. The noise was supposedly so bad that everyone on the base (and even off base) couldn't hear themselves think whenever the plane was started up. It would be fun to return one of the prototypes to flying condition, and take a tour of airports that have noise complaint problems from the surrounding community. Might let them understand that their existing noise isn't so bad after all! :nuts:
 
This is how you handle jet noise:


Planes Diverted From Dallas Airport During Neighbor's Noise News Conference

Mon, 22 May '06
See? Love Field Is REAL Quiet... Honest!

Relative quiet in the skies over a neighborhood where residents are holding a news conference to complain about airplane noise would seem to defeat the purpose of the news conference, right? Well, that appears to have been the case near Love Field in Dallas, TX last week, where Richard Medrano and his neighbors spoke with reporters about their recently-filed complaint against the airport.

As it turns out, however, that silence may have been at least somewhat by design. The Associated Press reports that Southwest Airlines -- the main player at Love -- diverted three of its flights from the airport over the course of the 45-minute news conference.

That was confirmed to the Fort Worth Star-Telegram by an FAA official, who says the flights were diverted at the request of Southwest Airlines.

Medrano, who also sits on the board of DFW International -- Love Field's main rival -- wants Congress to keep the 1979 Wright Amendment in place. That legislation limits the number of destinations available to flights from Love Field.

Southwest, of course, is lobbying to undo the Wright Amendment -- which it says unfairly hampers air carrier competition in North Texas.

In spite of statements from the FAA confirming the diversions, Southwest says it knows nothing about them... but that didn't stop Medrano from "thanking" Southwest CEO Herb Kelleher for diverting the flights.

It's not that bad, I've near a few of them.
