It's probably
one of the more cliche'd items about open-cockpit flying. You
tell folks you own an open-cockpit airplane, and they ask, "Do you
have a silk scarf?"
Well...do you?
I'll admit, the outright classic nature of it is one big reason I wear one. But, you know, they're more than just a fashion accessory.
This was brought out to me just last spring. I'd brought my white silk scarf home to wash it, and had hung it on the shower rod to dry (high enough that the wife's cats can't reach it, thankyew very much).
The aforementioned wife happened to take a look at it. "Looks like it's time you bought another one," she said.
I hemmed and hawed. "Yeah, it's not really whitening up, but they're supposed to look a bit grimy..."
She shook her head. "No, this one is worn out. Look at the holes!"
Sure enough, she was right. After 20 years of use, I had a number of thin spots in my silk scarf, and a couple of spots where it had been worn right through.
Pure fashion sense didn't put so many flight hours on the scarf that I wore it out. Over the years, I have come to recognize it as a necessary item of my flight gear. Why?
One simple reason: The planes were wide-open, cold winds have a tendency to blow down the neck of pilots' coats. They had two basic choices: Wear a coat with a high, close-fitting collar, or use a bit of fabric to plug the gap...e.g., a scarf.
But there's a problem with that high-fitting collar. A tight collar restricts the motion of the neck...makes it harder to look around, to spot the wily Hun. What's more, wool, linen, cotton, or leather tends to chafe the tender skin around the neck.
So a scarf makes more sense. But a conventional woolen scarf isn't much of an advantage. The scarf needs to be a soft, yet tight-weave fabric that slips smoothly by the skin while still barring entry to the cold winds.
Nowadays there are probably dozens of miracle fabrics that fit the bill. But to the early aviator, there was only one: silk.
A silk scarf is a perfect companion to the traditional leather flying jacket. The inside of the jacket collar is usually a bit rough, but wrapping a scarf around your neck fixes that problem nicely.
I'm not sure where the tradition comes of a white scarf comes in. It appears to be the color of the Army Air Force's issues scarves during WWII, but it seemed to have been common before that, too. It might be that the dyes of the day tended to run and rub off against the clothing and skin, and bleached white silk didn't have that problem.
It might, too, be related to the claim that pilots used the scarves
to clean the oil off their goggles while flying. A white scarf would
make sense, in that
case, as you could ensure that you used a clean spot on the scarf rather
than a part carrying dirt or oil.
{Note: After posting this, one poster suggested the reason was that the scarves were often made from parachute silk.... which wasn't dyed.}

Color
VariationsInterestingly, the poster for the movie shows Peppard with a RED scarf...and a frayed one at that!
And it looks like Bob Grimstead keeps that red-scarf tradition with his "Bristol Balderdash" Fly Baby. Interestingly enough, when the Merchant of Glenorchy online aviation collectables store turned Bob's photo into an art deco poster (with Bob's permission), they turned the scarf white....pretty much reflecting the current style.
Over
the years, I've seen any number of colors, including some that were printed
in patterns. I watched the cringe-inducing movie, "A Yank in the
RAF" recently, and the title character (Tyrone Power) wore some kind of
weird paisley scarf. Logo
scarves seem big, now.
Basically, you want to buy a six-foot, NON-FRINGED, silk scarf.
Why six feet? Because you are going to tie it around your neck, and wrapping it around your neck and getting it secured will take a considerable length of that.
Why non-fringed? Because the fringes rob a good six inches off the total length. And...well...they look a bit too, ummm, foppish for my taste.
Wearing the ScarfOne big problem with that: Due to the slipstream being deflected by the windshield, the Fly Baby cockpit is a low pressure area. The wind hits the windshield and gets deflected upwards then rolls under. Thus, the usual airflow past the pilot's head is FORWARD. Back when I wore cotton balls as temporary ear plugs, they'd occasionally come free. I'd see them go forward, then up until they hit the main slipstream.
Your scarf will do the same thing, too, if you're not careful...as this picture of Bob Grimstead illustrates. Yes, the red thing in front of his chest is his scarf.
If you want the classic look of a scarf fluttering in the breeze, it's easy enough: Just buy a second scarf and attach it to the aircraft's headrest. That'll put most of its weight outside the turbulent area.
So, what do you do with the scarf that you're wearing?
There are two basic knots you can use. I use the classic square knot. I start with the scarf in front of my neck, take both ends completely around, then knot them in front and stuff the loose ends down under my shirt. The ends aren't very long, so even if they come loose, they don't usually cause a problem. Being so short, they can't really get grabbed that strong by the wind. I zip the jacket up almost all the way, too.
The second knot
is something I call the "Hollywood Knot" It's not really designed
for open cockpits, but gives a devil-may-care look under the leather jacket.
The biggest problem with the Hollywood Knot is that the scarf ends are unsecured. Unless you make an effort to secure those ends, the scarf WILL billow in front of your face while you fly.
But, hey...it DOES look good, don't it?
The art of tying the Hollywood Knot has been lost for generations, but I think I have rediscovered it. It's basically a modified version of the standard double-Winsor knot, with the exception that the horizontal pass of the long end is left out.
Basically, you set up with one free end of the scarf very long, and the other very short. Cross the long end over the short end, bring it up the middle, take it to the side it originally came from, then back underneath again. Tighten the knot, then manually spread the top layer out.
I've added a visual guide to the end of this web page.
The top layer is essentially loose. If you put on a jacket, it will naturally form the billowy "V" shape around your neck. Without a jacket, the end hangs dashingly free.
If you wear one while flying, though, make sure the ends are secure.
Finally, be advised: Hollywood Knot is a fearsome weapon, especially coupled with a dazzling smile. Use it responsibly.
One addition, suggested by a friend's talk with a WWII aviator: If your scarf is long enough, take a wrap completely around your neck before starting with Step 1. In other words, hold the middle of the scarf in front of your neck, then wrap both ends around until they come out as shown in Step 1.
