Excellent visibility helps T-38 pilots fly tight formations.

Despite its radical appearance, the T-38 is a gentle airplane in the air, straightforward in character, almost viceless, and thoroughly conventional in handling. An unmistakable buffet gives ample notice of an impending stall. For a long time the aircraft refused to spin at all. The Air Force’s training command initially complained that the T-38 was too easy to fly, compared with the fighters for which it was supposed to be preparing new pilots. Gasich retorted that the Air Force ought to demand fighters that flew better—and that’s what eventually happened. Today’s fighters are so docile and forgiving that the T-38 is now, according to former instructor pilot Lewis Shaw, “the hardest airplane to fly in the Air Force’s fleet.”
It trains not only Air Force cadets, but test pilots as well. Says Northrop test pilot Roy Martin, “It replicates theory great; that’s what makes it such a marvelous teaching tool.” It flies just as textbooks say airplanes should. Lockheed Martin test pilot Dan Canin agrees with Martin up to a point, but adds that as far as test pilot training goes, the T-38’s main defect is that it’s too good an airplane—it doesn’t give students enough faults to identify. Canin’s favorite test pilot trainer was the de Havilland Beaver—“It had so many things wrong with it.”
Since Lee Begin first shaped it, the T-38 has continually inspired affection. Lewis Shaw still calls it “the 36-24-36 blonde on the beach.” Dan Canin raves: “I absolutely love the airplane. The T-38 and its siblings [F-5/F-20] are absolutely beautiful things…iconic, really…designed, it always seems to me, exactly as one would sculpt a fighter if he didn’t have to worry about anything practical…like fuel, weapon systems, etc. As we go exclusively with stealth designs, which are inherently fat to incorporate weapons internally, I doubt we’ll ever see fighters this good-looking again.”
Like all objects of infatuation, however, the T-38 has become encrusted with legend and exaggeration. It’s commonly said to roll at 720 degrees a second; the truth is 280 to 300, and in any case research suggests that anything above 220 merely serves to disorient the pilot. Another oft-repeated claim is that the T-38 climbs 33,000 feet a minute, even though the aircraft’s time-to-climb record, set by Walt Daniel in 1962, is three minutes to 30,000 feet. According to Northrop’s Roy Martin, a normal climb at military power—that is, maximum power without afterburner—is around 6,000 feet per minute.
Four decades have passed since the T-38 joined the Air Force. Its lines are no longer jaw-dropping; other airplanes have come to resemble it. It still clings to its old nickname “the white rocket,” but today’s pilots, comparing it with the F-15 and F-16, find the Talon underpowered. The thrust of present-day fighters is almost equal to their weight, and their maneuverability is superior to that of the T-38, which needs 10,000 feet to execute a loop and can’t maintain both airspeed and altitude in a 5-G turn. (Nevertheless, T-38s were good enough for the Air Force precision aerobatic team, the Thunderbirds, which flew them from 1974 to 1982.) A-10 and B-1 pilots are kinder to it. Beth Makros, a former B-1 pilot now instructing at Vance Air Force Base in Oklahoma, was surprised to find that she felt right at home when she first transitioned from the tiny T-38 to the nearly half-million-pound B-1. “It handled similarly,” she says. “Roll was similar, speeds are the same, it lands the same. They’re surprisingly alike.”
The T-38 does have faults. The J85 engines are temperamental at high altitude, and were prone to damage from ingested ice—the inlets are unheated—until the Air Force stopped flying Talons in icing conditions. The brakes, proportioned to fit into skinny wheels that are sized, in turn, to retract into the paper-thin wing, are barely adequate to stop it on a mile and a half of runway, even with a good deal of help from nose-high aerodynamic braking. Its original engine air intakes, optimized for supersonic performance, were too small to deliver sufficient takeoff thrust at high altitudes and summer temperatures.
The small, thin wing, only 25 feet in span, is responsible for the Talon’s most troublesome characteristic: its lack of lift response at low speed. Dan Canin explains that in a significant portion of the low-speed flight regime, the so-called “back side of the power curve,” the only way to gain speed is to lose altitude. “If you get slow with a big rate of descent near the runway, pulling the nose up will only result in the airplane hitting the ground in a more nose-up attitude—it won’t stop the rate of descent at all.” Landing the T-38 reliably requires precise speed and power control on final approach, and in particular not reducing power or raising the nose too early. The wing digs in like a shovel in mud, and once that happens, even the afterburners might not be able to pull it out.
That characteristic was tragically illustrated in 1966, when two NASA astronauts got into trouble at low speed while circling to land under a low overcast (NASA operates a large fleet of T-38s as trainers, space shuttle approach simulators, and astronaut runabouts). Pilot Elliot See kicked in the afterburners, but it was too late. The banking Talon hit the roof of a building and crashed into a courtyard, killing both pilots.

As Northrop test pilot Lew Nelson rolled down the main
Edwards A.F.B. runway in the first prototype YT-38 to lift
that white airplane into the air for its' very first flight
on the morning of 10 April, 1959,Air Force Captain Swart
Nelson deftly timed his descent in an F-100F to bring his
aircraft directly abeam Nelsons' as it lifted from the earth. In the aft cockpit of that F-100F, I strained to
control the Adrenalin which flowed through me, in order to
steady the 16mm Bell and Howell with which I was to film
this historic 1st flight. I was acutely aware of the fact
that this was an historic flight; and, that I was the only
photographer in the air to record it.
Out side of the birth of my son and my daughter, I'd have
to say that this; and subsequent moments filming various
stages of the Category I flight test program, stand out
as premier moments in my 79 years of life. And how very
gratifying to know that so many of these sleek little
white airplanes still perform the service for which they
were designed. What a testament to the quality of the
Northrop teams who designed, constructed, and tested this
machine.

While reviewing a prototype Angle of Attack system on a T-38 at Randolph AFB in 1969, The Chief of Ops, a bird colonel, expressed his view to me that the T-38 would satisfy the USAF Training Commands advanced training syllabus until the year 2020, or another 50 years. It appears that he was right since USAF recently completed retrofiting 500 T-38's with glass cockpits. This to allow for students to transition from the newer T-6, Texan ll primary trainers with glass cockpits that replaced the T-37 dog whistles with round dial cockpits. I take a great deal of pride in having been part of the T-38/F-5 engineering team.

The white beauty,
that´s what we german Students called it in Sheppard AFB.
My time on the T-38 started in July 1976 and ended with graduation in January 1977! The following 3.100 hours in the Phantom was great, but i´ll never forget the time in the T-38.
It´s amazing, that bird will be still flying when i´m long gone!

I was at Reese AFB June 76-until May 77 graduation from UPT and we met on the flight line at Sheppard in the fall of 76. I had hit a Hawk on TO on a return flight to Reese in a T-37 cross country night training ride and came back to Sheppard with fire lights illuminated and with a windshield full of blood!! What a return to Sheppard, as I had been there in '69 as an enlisted aircraft maintenance mechanic trainee! And, my friend, was in Germany at Rhine-Main 70-72 no less!! Who would have envisioned that 7 years later I'd be in the cockpit of my dreams. Well, not exactly yet, but I was on my way to a long aviation career!!
Respectfully,
Andrew Blaha, Colonel USAF (Retired)
Now, at 60 youthful years old, also a retired Captain from American Airlines.
All the best to you.

Flew the White Rocket as a UPT student at Reese in the early 80's and I still have the occasional dreams of the AOA indicator in the pattern.....Green donut all the way down final...manage throttles, don't pull the power until over the numbers and aero-brake. It's gratifying to know that I wasn't the only aviator who found the Talon a challenge to land.

Flew T-38 at Vance AFB. OK, as a 20 year old foreign student from Denmark. Those days formed me for the rest of my life. The experiences in the T-38, contact and cross-country, is among the very best experinces in my life, and I remember it as if it was yesterday. Nothing like it! Thanks.
Fly safe and enjoy.
