Mach 2

Found this little pin in a box recently. Not much to look at from a distance. Small F4 on it, but its the caption that catches the eye: Mach 2 Club, Phantom II.  The first reaction might be: “Is this a joke?”  No its not a joke.

Back in the 1970s, as a backseater, I did fly Mach 2+ in the F4 when I was a member of an FCF crew.   FCF – Functional Check Flight – crews took recently repaired F4s up and put them through extreme flying challenges to ensure that they were repaired before the next crew flew them.  One part of the FCF profile was to fly at speeds exceeding Mach 2.  Mach 2 is approximately 1,535 knots (nautical miles per hour) or 1522 miles an hour.

Now if you have seen the movie, The Right Stuff, you remember Chuck Yeager’s attempt to break the so-called “Sound Barrier.”   Breaking the “barrier”  was exceeding the speed of sound, about 761 miles an hour.  In the movie, Yeager is buffeted and banged about.  Its very dramatic, the small Bell X-1 is tossed around the sky and looks like it is entering a vortex of some sort.  Ominous.   On October 14, 1947, the Bell X1 – nicknamed Glamorous Glennis  after Yeager’s wife– became the first airplane to fly faster than the speed of sound.  In the movie it looks very dramatic.

So when people invariably ask: “What was it like to fly more than Mach 2?”   I answer:  “Its fast.”  But also very routine.   Fying the F4 at Mach 1 or Mach 2 didn’t have the same drama as Hollywood portrayed.  Much of the flying of a high performance jet is by the book.  Checklists govern every thing the crew does.  That includes flying Mach 2.  Both crew members are very busy performing the tasks assigned, checking to make sure that the plane performs as it is supposed to.    There is a shock wave but the crew doesn’t feel it as they are going faster than the speed of sound and ahead of the movement through the air mass.  The real indication of the speed is watching the horizon and the Mach meter and feeling the power of the two F4 J79 engines, the  inertial reel locking and being pinned to the seat.  FCF flights also include very high altitude flying, pulling Gs, and other stresses on the air frame.   I remember flying above 50,000 feet, the oxygen mask ballooning against my face, seeing the curvature of the earth.  Its the closest I ever came to being in space.  Then when it was over the AC asking on the ground, “how did it feel to go Mach 2.”If this sounds dry and prosaic, it’s the typical aircrew member take on what it was like.

It takes a poet to do justice to the experience.

Oh! I have slipped the surly bonds of earth,
And danced the skies on laughter-silvered wings;
Sunward I’ve climbed, and joined the tumbling mirth
Of sun-split clouds, –and done a hundred things
You have not dreamed of –Wheeled and soared and swung
High in the sunlit silence. Hov’ring there
I’ve chased the shouting wind along, and flung
My eager craft through footless halls of air…
Up, up the long, delirious, burning blue
I’ve topped the wind-swept heights with easy grace

Where never lark or even eagle flew —
And, while with silent lifting mind I’ve trod
The high untrespassed sanctity of space,
Put out my hand, and touched the face of God.

— High Flight by John Magee

That is what it’s like.

    What a beautiful poem! Thank you for sharing it. I can’t imagine what that must have been like to fly that fast.
