SR-71 Blackbird

Last edited Mon Dec 15, 2014, 04:12 PM - Edit history (1)

One of the most beautiful airplanes ever. I saw and touched one of these retired birds at a museum and was struck by its covering-rough and coarse like running your hand over calloused skin.

A single prop private plane is puttering along less than 100 mph, radios the tower for some sort of check.

F-22 pilot decides to razz the little plane that he's going about 500 mph.

SR-71 radios in that he's going Mach 3.

Back before everyone has GPS, it was popular to ask air traffic control for your ground speed, which is displayed on their scope, which saved the pilot the trouble of using the old whiz wheel to figure it out.

There were a lot of things we couldn't do in an SR-71, but we were the fastest guys on the block and loved reminding our fellow aviators of this fact. People often asked us if, because of this fact, it was fun to fly the jet. Fun would not be the first word I would use to describe flying this plane. Intense, maybe. Even cerebral. But there was one day in our Sled experience when we would have to say that it was pure fun to be the fastest guys out there, at least for a moment.

It occurred when Walt and I were flying our final training sortie. We needed 100 hours in the jet to complete our training and attain Mission Ready status. Somewhere over Colorado we had passed the century mark. We had made the turn in Arizona and the jet was performing flawlessly. My gauges were wired in the front seat and we were starting to feel pretty good about ourselves, not only because we would soon be flying real missions but because we had gained a great deal of confidence in the plane in the past ten months. Ripping across the barren deserts 80,000 feet below us, I could already see the coast of California from the Arizona border. I was, finally, after many humbling months of simulators and study, ahead of the jet.

I was beginning to feel a bit sorry for Walter in the back seat. There he was, with no really good view of the incredible sights before us, tasked with monitoring four different radios. This was good practice for him for when we began flying real missions, when a priority transmission from headquarters could be vital. It had been difficult, too, for me to relinquish control of the radios, as during my entire flying career I had controlled my own transmissions. But it was part of the division of duties in this plane and I had adjusted to it. I still insisted on talking on the radio while we were on the ground, however. Walt was so good at many things, but he couldn't match my expertise at sounding smooth on the radios, a skill that had been honed sharply with years in fighter squadrons where the slightest radio miscue was grounds for beheading. He understood that and allowed me that luxury.

Just to get a sense of what Walt had to contend with, I pulled the radio toggle switches and monitored the frequencies along with him. The predominant radio chatter was from Los Angeles Center, far below us, controlling daily traffic in their sector. While they had us on their scope (albeit briefly), we were in uncontrolled airspace and normally would not talk to them unless we needed to descend into their airspace.

We listened as the shaky voice of a lone Cessna pilot asked Center for a readout of his ground speed. Center replied: "November Charlie 175, I'm showing you at ninety knots on the ground."

Now the thing to understand about Center controllers, was that whether they were talking to a rookie pilot in a Cessna, or to Air Force One, they always spoke in the exact same, calm, deep, professional, tone that made one feel important. I referred to it as the " Houston Center voice." I have always felt that after years of seeing documentaries on this country's space program and listening to the calm and distinct voice of the Houston controllers, that all other controllers since then wanted to sound like that, and that they basically did. And it didn't matter what sector of the country we would be flying in, it always seemed like the same guy was talking. Over the years that tone of voice had become somewhat of a comforting sound to pilots everywhere. Conversely, over the years, pilots always wanted to ensure that, when transmitting, they sounded like Chuck Yeager, or at least like John Wayne. Better to die than sound bad on the radios.

Just moments after the Cessna's inquiry, a Twin Beech piped up on frequency, in a rather superior tone, asking for his ground speed. "I have you at one hundred and twenty-five knots of ground speed." Boy, I thought, the Beechcraft really must think he is dazzling his Cessna brethren. Then out of the blue, a navy F-18 pilot out of NAS Lemoore came up on frequency. You knew right away it was a Navy jock because he sounded very cool on the radios. "Center, Dusty 52 ground speed check". Before Center could reply, I'm thinking to myself, hey, Dusty 52 has a ground speed indicator in that million-dollar cockpit, so why is he asking Center for a readout? Then I got it, ol' Dusty here is making sure that every bug smasher from Mount Whitney to the Mojave knows what true speed is. He's the fastest dude in the valley today, and he just wants everyone to know how much fun he is having in his new Hornet. And the reply, always with that same, calm, voice, with more distinct alliteration than emotion: "Dusty 52, Center, we have you at 620 on the ground."

And I thought to myself, is this a ripe situation, or what? As my hand instinctively reached for the mic button, I had to remind myself that Walt was in control of the radios. Still, I thought, it must be done - in mere seconds we'll be out of the sector and the opportunity will be lost. That Hornet must die, and die now. I thought about all of our Sim training and how important it was that we developed well as a crew and knew that to jump in on the radios now would destroy the integrity of all that we had worked toward becoming. I was torn.

Somewhere, 13 miles above Arizona, there was a pilot screaming inside his space helmet. Then, I heard it. The click of the mic button from the back seat. That was the very moment that I knew Walter and I had become a crew. Very professionally, and with no emotion, Walter spoke: "Los Angeles Center, Aspen 20, can you give us a ground speed check?" There was no hesitation, and the replay came as if was an everyday request. "Aspen 20, I show you at one thousand eight hundred and forty-two knots, across the ground."

I think it was the forty-two knots that I liked the best, so accurate and proud was Center to deliver that information without hesitation, and you just knew he was smiling. But the precise point at which I knew that Walt and I were going to be really good friends for a long time was when he keyed the mic once again to say, in his most fighter-pilot-like voice: "Ah, Center, much thanks, we're showing closer to nineteen hundred on the money."

For a moment Walter was a god. And we finally heard a little crack in the armor of the Houston Center voice, when L.A.came back with, "Roger that Aspen, Your equipment is probably more accurate than ours. You boys have a good one."

It all had lasted for just moments, but in that short, memorable sprint across the southwest, the Navy had been flamed, all mortal airplanes on freq were forced to bow before the King of Speed, and more importantly, Walter and I had crossed the threshold of being a crew. A fine day's work. We never heard another transmission on that frequency all the way to the coast.

For just one day, it truly was fun being the fastest guys out there.

The story refers to "LA Center", the Los Angeles air route traffic control center. LA Center currently resides on the Plant 42 complex in Palmdale, CA, home of "The Skunkworks" and sits across the street from an outdoor aviation museum where two of the airframes are on display.

That story has been around for some time, and I have to question its validity for a couple of reasons.

For one thing, anything above 60,000' is uncontrolled airspace, meaning ATC isn't tracking you and isn't in radio contact. Air traffic control radars and computers aren't designed to track 13 miles up, although it may have been technically possible, and they may have wanted to remain in ATC contact for whatever reason.

The other thing seems a bit more unrealistic. Also from the same FAA publication, ground speed readout on the controller's display is limited to 2 digits with a zero implied for the first digit, which means that 990 kts is the highest ground speed they can display. So a value of 1,842 just doesn't make sense because they wouldn't be able to see the first and last digits. The HTML version of the AIM is impossible to read. See page 4-5-3 on the PDF version. Now this is the current version and I realize the story is from many years ago, but I've been reading the AIM for more than 30 years and I don't think they have changed the page much, if any, and the capabilities certainly haven't been decreased.

I cry a little inside when I watch "The Right Stuff."

Sixty years ago, We The People actually had dreams and aspirations.

We looked to the sky and wondered, "what does the world look like from up there?" Then we built a rocket safe enough to strap a human being to, and found out.

We looked at the moon and wondered, "is that thing really made out of green cheese?" Then we went up there and found out.

We stood atop the Rockies, looked at Chicago, and said, "it's only about 1600 miles to there. Why can't I drive there in two days?" Then we built a nationwide network of highways that allows us to do that.

Now we look at the $1,000 tax bill on our $100,000 incomes, and wonder, "why can't they make this any lower?" Then we buy a Congressman and make it happen.

Every nice thing in your life has, somewhere in its heritage, a big chunk of tax money. Thanks to those rat bastards in the GOP, all that is in danger of going away - they'd rather use your taxes and my taxes to offset reductions in Alice Walton's taxes.

They take off with a minimal fuel load and once they attain top speed the skin of the plane expands and seals.

The problem was they couldn't deal with the extreme temperature differential and create fuel tanks that wouldn't leak both at static and normal operating temperatures. So it was just one of the problems of the design that wasn't solved and had to be dealt with operationally.

The gauges themselves run on either electrical or vacuum, but they are considered ancient compared to the electronic instruments which have replaced them, thus the implication they run on steam power.

This is another example of why I enjoy DU.

I heard, many years ago, that instruments from prop WWII planes wouldn't work
in jet planes.
The story, as i understood it, was that the instruments in their new environment wouldn't
work because there wasn't enough vibration.

Myth?

Most of the primary instruments are gyroscopic, so I suppose it's possible that those of the period were developed for high vibration environments of very highly powered piston engines and wouldn't work properly in jets. I have a friend that has an operational T-28A and the primary instruments in his plane are basically the same as mine, and I know of no reason why they wouldn't work in a jet. Another guy I used to know owned an F-5 and I couldn't tell any difference in his primary instruments.
