We have a trainer on display here at the science museum, they disassemble it for shipping.

I saw this one at the Udvar-Hazy annex of the Smithsonian National Air & Space museum out at Dulles airport. Very cool place to visit if you're in the D.C. area.

When I was there in the late 70's (when they made L-1011s there) it was also a training area for a couple of airlines. From the office it was interesting to watch DC-10s bounce in on one wheel and take off with engine failure yaw.

555th , Ubon, he probably flew under Robin Olds who was wing commander there of the 8th wing.. Look up Operation Bolo.

Brian is a legend. His story is truly inspirational. (& there go any excuses I ever had about anything)

I read that story before, and it was brilliant then, hearing it told even better.

Here is a fighter version (production 3)
I worked with a guy associated with the SR71 who said to get back to the US from Vietnam they would point the nose up, climb until they flamed out, drift through low space until the engine would relight and repeat. Does this sound feasible? ![]()

It's well worth the time to watch the videos linked here in this post.
I just finished the hour long one. Very informative and well done. The SR's that overflew Vietnam flew out of Okinawa, not the US.

Another reason why the zoom climb to space story does not add up, is that the fuel has an extremely high flashpoint, and need special chemicals to fire the thing up.
So would anybody risk flaming out both engines if those engines are so hard to ignite. With such an exclusive, expensive plane? doubt it.

From what little i know of these planes, at the speed they flew the tiniest uncontrolled change any of the three axes could have been disastrous.
If an engine flamed out at mach 3 I'd be surprised if the plane didn't disintegrate. |

The Vietnam story is crap, as they carried about 80,000 pounds of fuel and that gave them a range of a littlre over 3,300 miles. No way they could have made it from Vietnam to the US in that way. They did occasional long trips but they refuelled a bunch. There was always a limit to how far they went, at they only carried enough TEB to light the engines (or engage the afterburners) 16 times. Not only did they use a shot of TEB when lighting the engines off, they used a shot every time they moved the throttles to the afterburner position. Considering they cruised with the afterburners lit, this meant that every time they got off of a tanker, they had to light the burners again. There was another way to light the burners but i don't think it would have re-lit a flamed out engine.
Inlet unstarts were a problem and they could result in the afterburners flaming out. One other consideration is that they used the fuel as hydraulic fluid for some of the systems, so running out of fuel was not an option. They often had inlet unstarts at high mach numbers that were bad enough to bang the pilots head off of the side of the canopy. Aileron authority was inadequate above 75,000 feet to deal with really large problems (an unstart caused yaw, pitch and roll problems immediately) so these planes were flown very carefully and precisely at high speeds and altitudes. I don't know that they've ever declassified the max altitudes they reached but they were nowhere near what they got out of the NF-104A. JR |

Wiki:
It (NF-104A) quickly established a new unofficial altitude record of 118,860 feet (36,230 m) and surpassed this on 6 December 1963 by achieving an altitude of 120,800 feet (36,800 m). ![]() Last edited by sammyg2; 01-08-2017 at 10:59 AM.. |

I attended an electronics class for two weeks back in '65 at Beale AFB (CA) where there was a squadron of them. Never was able to get too close, however. Just looking at them took my breath away. Interesting stories from the maintenance guys.
