Today, though, what looked like an F-18 flew over. Wow. I haven't
seen too many fighters in my life (still have yet to see a "real" air
show).

Duluth is only 150 mile straight up the freeway from MSP (Mpls/St. Paul)

We want to get up there for the Air Show.

If you do a search for turboprop noise in the NASA archives you will
find the info - the surprising thing to me was that the noise levels
were about equal clear out to the sixth harmonic. Yes, the XF84H was
loud. But the Saturn 5 was mucho louder, but you couldn't get closer
than about 8,000 yards. OTH, standing about 3 feet to one side from
the nozzle of a J79-17 at max power is verrry interesting.

I'll second that motion.

While not a J79, the engine on the F-16 is quite impressive up close.
Did a job shadow with an F-16 crew chief and did final checks with him.
One involved lying under the aircraft and checking something just
forward of the afterburned turkey feathers. The noise was punishing.

Already on the calendar. I'll be there!

You want loud? Or annoying?

UH-1H doing a nice slow deceleration at low tq settings will produce a
popping sound that is easily heard for more than a mile. And it last a long
time.

I was flying a CH-47D at 165 knots and the folks on the airfield said they
heard us coming for at least five minutes before they saw us. Man she was a
good ole bird.

Don't you all just love the sounds of freedom.

I reside about 6 miles off the departure end of MSP runway 12, so I'm
used to hearing a lot of jet traffic. I've only lived here for 6
months but I quickly adjusted to the noise. It's acutally not that
bad, excepting the venerable DC-9.

Today, though, what looked like an F-18 flew over. Wow. I haven't
seen too many fighters in my life (still have yet to see a "real" air
show). That thing peeled off to the southeast with a thunder that
even the DC-9 in full song can't match.

She was probably climbing through 3 or 4 thousand when I looked up.
Are afterburners used during departure? If not, I can't imagine what
_that_ sounds like.

Scott, I'm the same distance off the approach end :-) Saw the same
airplane, I think. I took it for an F-15. Seen several T-37s
overhead lately, too, plus a pair of T-38s a week or two ago. A year
or two back when the BUFF came to town it came in right over the
house. We were outside; my wife looked up and said, "I'm sure glad
that's on OUR side!"

Saw a Vulcan at an airshow some years back - it was making its
farewell tour before being retired. I can understand why the Falkland
sheep were scared out of their coats! Like a flock of banshees.

My vote for best loud airplane sound, though, would have to go to the
B-36. Rent the Jimmy Stewart classic, "Strategic Air Command" and
turn up the surround-sound.... Folks who heard them fly over the
Great Plains say that you would hear that drone for hours as that
six-ply contrail slowly crossed from horizon to horizon.

The sound of freedom indeed!
