In '83 we got the entire AT-38 fleet painted in a standard blue-blue-gray gloss camo. Affectionately known as "Smurf Jets". Spins in a T-38 are unrecoverable as well, but also virtually unattainable. Not sure if they did this while you were at UPT Ed, but early on in the T-38 syllabus they take you out and demo how resistant the T-38 is to spin. The instructor flys because if they let a student try, you know they'de get it into a spin BUFDRVR "Stay on the bomb run boys, I'm gonna get those bomb doors open if it harelips everyone on Bear Creek" |

The procedure which MIGHT get a spin was full aft stick at max rate. But, it had to be done after a nose down unload excursion at nearly max rate as well. So, pump the nose down hard then quickly reverse and bang the pole back into your lap. This had to be done in an inverted position, as I remember it, in order to get that last bit of pitch excursion -- from full nose up (inverted) to max rate nose down in order to get the Talon to spin. I never wanted to walk home, so I wouldn't know from personal experience. Jack |

(long Snip)
We taught rudder rolls, over/under, loaded/unloaded, with or without full aileron deflection. No spins. We taught gun defense jinking as: 1.) check airspeed to be sure you're below corner velocity, 2.) now plant the stick in random corners of the cockpit at full speed. 3.) lather, rinse, repeat. No spins. It just won't spin. Run it straight up to zero airspeed, put in full rudder and max aileron--no spins. It simply swaps ends. Ed Rasimus Fighter Pilot (USAF-Ret) "When Thunder Rolled" Smithsonian Institution Press ISBN #1-58834-103-8 The T-38 dash one used to read "If the aircraft is allowed to enter a stabilized spin loss of the aircraft and crew is probable." If I remember correctly it took the Northrup test pilots several weeks to learn how to make it spin. Fortunately their aircraft were equiped with recovery chutes.

Trust me, they wouldn't be able to spin the T-38. I guess the IP demo was done so they could accurately perform the demo? Got a book review brief on your book today Ed (yes,yes I'm going to get it!). Only critique was that you used too much jargon. The review was done by a Comm officer.

If you don't hurry, you'll be way behind when the new book comes out in February. I actually grab the copy that the comm guy used and read up to page 20 while half paying attention to the other book reviews. I was hooked by page 20 so I'm resolved to buy it this weekend.

The airplane will spin, but it is a decidedly unnatural act and AFAIK only been accomplished in very abusive flight testing at Edwards. The F-5 model with the long pointy nose (the F, maybe) spun more easily and was extremely hard to recover. It took jettisoning the canopy to break the spin, in fact. The T-38 and the other F-5s weren't nearly so difficult to recover, but they weren't really easy, either. The gouge about "easy to spin, easy to recover; hard to spin, hard to recover" has a certain amount of truth to it. We, Dryden, were spinning (intentionally) a 3/8ths model of the F-15 when that F-5 got into trouble. Ken had given a briefing on spins, including the vulnerability of long pointy noses, to a group that included the AFFTC commander about two days before the F-5 spin. The commander called our director and asked if anyone else had any predictions he should know about. Did you ever run into the inverted pitch hang up on the T-38? It's well-known in the Flying Qualities community but I haven't heard that many pilots talk about it. I think the F-5s had it, too. Mary -- Mary Shafer Retired aerospace research engineer |

The gouge about "easy to spin, easy to recover; hard to spin, hard to recover" has a certain amount of truth to it. The E's and F's we had at Top Gun in '81 had the shark nose mod and leading edge extension. That they were spinnable was proven (along with difficulty of recovery) when the skipper (MiG killer Roy Cash) had to return one to the taxpayers. We all talked about jettisoning the canopy and, in the case of the 2-seaters F's, directing the backseater to eject, in attempts to get some nosedown pitch (the backseaters used to point out that having the frontseater leave, instead, was more likely to work-- particularly since HE was the hamburger who had gotten you into that fix anyway--given the realtive positions of the seats). Nobody ever had to test the backseater idea, and I am skeptical about the canopy idea. If you've got no airflow anyway, what good to throw away the window? Then again, what do you have to lose?
