  1. It was a controlled explosion. It's not literal that they packed it full of explosives like a stuffed turkey and up it went into the air. The quote was from a member of the assault element so their choice of words. Reads better in their book and gives a dramatic mental image of the event. Also, Thermite grenades are stable until ignited and no more dangerous than carrying frags, flash bangs, or anything that goes boom, bang, burn on a helo for an insertion or extraction. The nature of the game is inherently more dangerous than your loadout not to mention you typically 'safe' everything.
  2. Come on now 11bee, there is nothing strange here and it's common practice to destroy material via the trusty and true Thermite grenades or hit it with an air strike even. I would say the ground element did a much better job than you see here courtesy of Sappers at Bien Hoa AB in '68. Melting airframes are nothing new. The SEALs are reported to have packed the downed helicopter with explosives and blew it up. This after the pilots and aircrew, destroyed avionics and coms prior to their exfil.
  3. Saved this for occassions such as this one: Huey colors - Rotors, rotor head, scissor, push rods, links, swash plate and mast Viet-nam era UH-1 pylons (B ,C, D, H, and M) were all painted roughly similar, and components were mixed and matched with out regard to color. So you could have a pair of "drive links" for example of which one was gloss light gray, and the other being, just anodized and left that metallic silver color. Mast boots were varied from orange to red to black. The slicks (D&H) had one boot above the scissors and sleeve assy, while the guns (C&M) had two, one above the scissors and sleeves, and one below from the swash plate up to the scissors sleeves. The later protected the "uniball" Teflon coated bearing surface on which the swash plate rode. D&H models used a "u-joint" arrangement not unlike that found on an auto drive shaft. Swashplates were generally just coated and left to the elements. Some however, were painted that light gray during overhaul or repair. Swashplate and support assemblies were generally treated alike (being one assembly.) The mast is a steel alloy and is plated in a process known as Cadmium Plating giving it that silver-goldish color. The same can be said for the Yoke (center) of the main rotor hub. Blade grips, that part of the hub where the main rotor blade is attached to the hub is aluminum and was almost always Gloss Light Gray. On the guns, a plastic dust deflector was attached to the leading edge of the grip assembly, this was left it's natural primer grey looking color. (Similar to the color of the floor and some sound proofing blankets on the bulkhead.) Stab bar is subject to all of the above being made up both steel (outer bar and counter wights), and aluminum, the inner bow shaped pieces being aluminum. Hardware was often replaced on the pylon at the periodic inspection (100 hr) and maybe either gold Cadmium or Steel Gray/Silver color. Tail Rotor as above Yoke the gold Cadmium or Steel Gray/Silver color. Grips are painted the Gloss Light Gray. Huey trivia...For maintenance purposes a small dot of paint was placed on each component Red on one side, White on the other denoting the left and right side of the rotor system. Typical write up might be "Red scissor arm has axial play." or "White mixing lever has radial play." (We were lucky the crane drivers had Red, White, Blue, Yellow, and Black to contend with....)
  4. 89-0130 was a conversion to CH-47D from CH-47C. Image from 1 August 2018 147201 Boeing CH-147 CH-147D Chinook first date: 28 December 2008 - Accepted at Kandahar Originally built as CH-47C, US Army serial number 68-16017, company number B.609. Converted to CH-47D, new serial number 89-00130, conversion number M.3284. Over 39 years old when supplied to Canadian Forces. Purchased second hand from US Army for use by Canadian Forces Joint Task Force Afghanistan Air Wing at Kandahar, Afghanistan. In storage at Davis-Monthan AFB in US, arrived on 22 September 2011.
  5. There are two versions Fireball put out. Here is my 4 color profile . Note the color differences in mine of the top two Seawolves. They have the same Modex/writeup but are colored differently. Mine is also 1/48
  6. When MAG 16 was at Phu Bai they did not have PSP (Pierced Steel Planking) although they did have revetments and despite peneprime sprayed surfaces (tar sprayed dirt and rock to reduce brown outs resulting from aggregate dust and to limit FOD) they still had fairly dirty skids since you got the kit to practice weathering techniques. You can see some good amounts of fouling and wear on these slides including spilled fuel. This is before MAG 16 moved to Marble Mountain Air Field MMAF outside of Da Nang. The last slide here shows how dirty the tail became with soot from the exhaust. If you want to skip Vietnam and go with Kit decal options here's your Huckleberry @ NAS Glenview, Illinois 2 AUG 1974. If you need Hi-Res I have these in original format which is 1600x1800.
  7. Those are called Dynamic Stops In Short 4th not shown in your image fully engaged in flight. 3rd position as you have them is closer to lower rotor RPM as indicated by the image of the crew member clearing the FOD intake filter and the 3rd position in the take off image. Final image you cant even see them as they are bucked up against the underside of the 540 rotor head. Note the pitch of the blades in the last two images is the same but the rotor RPM is likely still coming up on the image of them nose low and moving towards ETL Effective Translational Lift.
  8. Just cast your figures after you sculpt them and use non-sulfuric clay or better yet resin. Most polymer clays have sulfur and will also melt plastic on kits. I made that mistake building B pillars and the overhead console. Any new updates?
  9. From Combat After Action Report - Airmobile Operations in Support of Operation Lam Son 719 (101st Airborne Division February 1971 thru 6 April 1971 dated 26 July 1971 "Throughout the operational area the NVA deployed an extensive, well-integrated, highly mobile air defense system which included large numbers of antiaircraft weapons of several calibers, the basic weapon being the 12.7mm machine gun. (Figure 1-7) Some antiaircraft weapons were apparently radar-controlled. " From 101st Airborne Division (Airmbole) Final Report Airmobile Operations in Support of Operation Lam Son 719 8 Feb - 6 Apr 1971 dated 1 May 1971 Camp Eagle, RVN Antiaircraft Engagements "In all cases where antiaircraft weapons were encountered, the 2/17 Cav requested TAC air, since the USAF has the standoff range and the fire power to engage AA weapons at a more acceptable risk level than does the Cav with organic gunships. When the Air Force had higher priority missions and was not available for such support 'organic aircraft on occasion engaged and destroyed AA weapons as large as 37mm. However, 23mm and larger were usually not engaged but marked for a FAC. AA engagements tactics varied from troop to troop, but generally the concept was to us as many gunships as possible, attacking simultaneously from different directions. If, as in the first month, OH-6A's were with the team, they were put in orbit out of effective range until the gun was destroyed. The most difficult aspect of engaging NVA AA weapons was to pinpoint the exact location of the weapon. The NVA had excellent fire discipline and used mutually supporting positions. Once a weapon was pinpointed, the AH-1G had a range standoff advantage over the 12.7mm and 14.5mm. Flechettes, HE and WP rockets and the XM-35 20mm gun if available were all used in engagement. The most significant AA threat faced by the Cav was the 12.7mm heavy machine gun. The NVA employed large numbers of these weapons, and located them so as to be mutually supporting along the helicopter approach routes. As far as can be determined the Cav lost no aircraft to weapons larger than 12.7mm, although several hits were recorded from 37mm airbursts. To counter the 12.7mm threat and still not become unacceptably vulnerable to larger caliber fire, most Cav teams operated at 3500 feet AGL to 5000 feet AGL, except for one AH-1G operating low and fast to detect targets." Also add 57mm and SA-7 missiles.
  10. You're welcome. I wouldn't bet that the report no longer exists. In fact I am sure it's out there. Plenty of information I uncovered in my research into SEANITEOPS existed in multiple places and required a declassification request as well. There are doctorate papers on DTIC that reference the report you are after for those specific systems. You will just need to dig harder. The link I sent is a path forward with some chronology as well as 3 possible HUMINT sources to search out. Are you only looking at US DoD programs? Only reason I ask is because another avenue is the Spanish Navy Fleet Air Army as they flew the Hughes500ASW from the Dedalo R.01 aircraft carrier (former USS Cabot CVL-28) and more typically from the destroyer Blas de Lezo. The Spanish 6a Escuadrilla was commissioned in 1972 with the Hughes 500ASW, thirteen initially with 11 still in service in 1982. They carried 2 Mk44 or 46 torpedoes, only 1 torpedo was carried when equipped with the AN/ASQ-81 MAD (Magnetic Anomaly Detector). They were also capable of carrying a 7.62 minigun on their port side and in the early 80s were slated to replace the AB-47s in the Naval Fleet Air Army.
  11. What you are after was conducted by NADC According to "History of the Naval Air Development Center" documentation at DTIC. According to this document there were recorded interviews Tape 13 specifically with Richard James among others, pg 53-54. If anything this is a useful index for it's timeline. https://apps.dtic.mil/dtic/tr/fulltext/u2/a123645.pdf DTIC does in fact have quite a large number of Navy documents and more controlled documentation if you have a CAC card. NADC was permanently closed in the 90s as part of BRAC. It was moved to NAS Patuxent River @ Lexington Park, MD. In 1992 BRAC pushed the NADC Navigation Department (Code 40) to transfer the NCCOSC (Naval Command, Control and Ocean Surveillance Center) Research, Test and Evaluation (RDT&E) Division to San Diego, CA. NCCOSC works with Space and Naval Warfare Systems Command (SPAWAR). SPAWAR supports over 150 programs managed by the Program Executive Office (PEO).
  12. Nicely done and you cant beat the community effort. Hand salute!
  13. I now pronounce you man and Cobra. Also here are two shots of Whiskey for you on the house! Both 1990 Van Nuys Air National Guard base before everything moved to NAS Point Mugu
  14. I'm setting the Way Back (WABAC) Machine for December 1986 to check out the Marine Corps AH-1W Super Cobra. Sherman and Peabody were in the Army National Guard so all they had were APH-1 and APH-5A helmets. They are also not wearing their Nomex but beg you to show mercy on them and not give them a bad OER or NCOER. As stated they are Army National Guard which means they routinely fly naked. Sorry about that! This article first appeared in 'Combat War & Weapons' published by Modern Day Periodical, Inc. in December 1986. Click for a 150 dpi version that will open in another tab at a more readable version. I like what Col. M.F. Pixton III had to say about the Apache on Page 4. I can only image what the 'M.F.' stood for in Col Pixton's name. =) Also, sorry for the wrinkly last few pages which were the result of a damp basement. I promise I was not gesticulating to helicopter pictures again although my wife has actually said these words to me, "I'm dead serious. It's the Huey or me! Take your pick!" =)
