Keith Anderson sent me these photos asking if they were from an F-106. Here's his message:
I was wondering if you could confirm that the enclosed pictures are of a F-106 Pitot Boom. I had pulled it out of a junk pile recently outside one of the old supply buildings undergoing renovation up the old Loring AFB, ME
Thought I'd send it over here for discussion.

Sure doesn't look like one to me, looks to big around and to short. There isn't an opening on the end for the pitot input, and one way to check it for sure would be to look towards the back end of the metal part before it's in the boom and check for the static holes, 2 on top and 2 on the bottom, and one drain hole a little further back from that.
But basically it looks to big around and to short to be off a 106.

Yea, I don't think it was a six tube either. The pitot itself doesn't even looked tapered enough. Our tubes didn't have that step-down look, it was a long clean taper that allowed for easy Never Dull cleaning  |

That reminded me of the pitot tube on 57-2533 on display at Kelly. Notice anything wierd for a display on a pole?  I don't know, maybe they want to keep water, or bird stuff out of it. I would think a spot weld, or sticking a dowel in the opening would work better for aesthetics! It just struck me as funny; like they didn't want anyone to bump into it. Mark  Close-up...  |

Yea, this shot is a good example of the taper I was talking about. The entire tube has a nice taper to it, large in the rear, thinner up front. |

An even better shot of the same pitot tube on 57-2533. Notice how it narrows, then has a slightly larger "bulge", then goes to a point. Mark  |

I'd forgotten about the screws that hold it on to the tube.

I believe it is for at least 2 reasons- 1. depth of field on the camera would tend to make the end that mounted to the radome look smaller, like the boom or mast was tapered the wrong direction.... 2. there were at least 3 different pitot heads used on the six and they were all interchangeable with each other.......What other aircraft stationed at Loring used a pitot boom that was 4-5 feet long and painted red and white or used red and white reflectorized tape?..... Photo isn't that great, the lack of a pressure inlet port could be nothing more than being plugged with corrosion.... The Old Sarge could be some track star lost his javelin?  ? hey MacGeep, ask Andy to take some more photos and measure the diameter at each end of the boom. Verify that the inlet for the pressure port is/is not plugged |

Here's another one. No way that tube is tapered.

Now, that said, I really don't know if this is off a Six, or a Duece, but those are the only two that make sense. Especially since I wasn't there! Mark |

Thanks for all of your input on the "Pitot Boom",i thought it was worth looking into since 106's were up at Loring. Here are the measurements- overall length 53 1/2", foward taper from point 5 3/8",
length of main body 41 1/2", rear taper 6 1/2". Diameters- foward taper 11/16", main body 1 1/8", rear taper 15/16" then down to 13/16".
The red and white markings are paint and look to be original, the tube is all steel. I cleaned it up a bit more but do not see any inlet holes toward the rear or ones that have been sealed, the foward tip appears to be solid. I have viewed 100's of F-106 pics and most are hard to see detail of the boom, some have the same red and white stripes others black and yellow, some straight, some swirled or twisted. Some have the taper of the boom continue the whole length of the the tube. Does anyone have a T.O. for the F-106a that show dimensions for the pitot boom?

Here's another one. No way that tube is tapered. Talking about the mast or boom itself, not the pitot tube.. The end that mounted on the radom was called the butt.......That would be the larger end.... Even the boom of the Deuce was tapered, only shorter, but the Deuce was never at Loring, unless it was a transient, and then the home team would have taken the defective boob home with them.... As I said there were 3 alternate interchangeable pitot tubes used . Keith, what are the diameters of the painted ends only? |

Measures pretty close to the front half of a javelin specs: uk.answers.yahoo.com/question/index?qid=20090817040817AARzqbEHere's a F-106 pitot boom at Castle Air Museum. The butt end close to the radome would measure about 3 inches in diameter and taper to around 2 inches where the tube goes into the boom. Seems I remember we had one replaced at Castle and I was surprised how heavy it was. I think the real F-106 boom was pretty sturdy and weighed about 20-25 pounds. Guess it had to be in order to withstand extra drag at high yaw and pitch angles at high speed. Could the boom you have possibly have been hand fabricated to substitute for the real thing that might have been missing from a F-106 static display? Maybe we can get Ralph Robledo to measure the one at CAM and let us know. Another thought - could it have been off an F-100? They had a hindged boom that could fold vertical - see picture Click here |

My fault, I thought the 27th was at Loring when they had Dueces. I got that off of Wiki, so that explains my error. Sorry about that. (I guess they were at Griffis with the Dueces?) Anyway, I found this photo from Bullhunter. It's a bit hard to really see, but this is off 56-0459 on display at McChord. (Try zooming in with the % button in the lower left of your screen if you have it.) Mark P.S. I threw the javelin in high school, and never saw one tapered like that.  |

Don't think thats a F-106 Pitot tube There is no Pitot input and no Static holes on top. It could be a test probe that was used to leak ckeck Pitot Static adators and stuck in this boom. Also there was 4 screws that mounted the Pitot tube to the boom and a mesh ring at the end of the boom where it hooked up to the radom and had 4 allen screws to mount the boom to the radom.

Again alot of good input, The diameter of the painted area is 1 1/8", I don't think it was fabricated as a dummy for a static display, by the looks of it i would say that this tube is about 30-40 years old, i've thrown out the javelin theory, does'nt make sense to find something like that sitting in a corner or hidding behind a beam in an air force warehouse for all these years and the fact that the painted stripes and length do match some photos i've seen, but not the diameter. I'm also thinking it may not be a pitot tube because of the lack of an inlet port in the nose of it. Did any aircraft use just a "dummy" boom or probe? the 106 boom in the picture is much fatter at the end and the taper goes the whole length gradually. F-102's where up at Loring 1957-60, but again looked through a lot pics, hard to see the booms close up, but the red and white stripes do match in a few. see pic. :  Attachments:

Here is some more pics of what i have, thickness and the aft end, also a pic of a f-104, its boom does not seem to taper the whole length. Were the pitot tips of the booms removable? i'll keep searching, thanks for everyones input. Keith : |
