      Ongoing DDoS Attack causing Forum Slowness   26/04/17

      In case you have missed the announcement, the reason that the forum has been slow at times since the minor version update the other day is due to a Denial of Service attack, brute force attack on our email, and judging by the lag with our FTP response, that too.  If you're feeling like you're experiencing a glitch in the Matrix, you're not wrong.  This is the same MO as the attack in September 2016 that occurred when we transitioned to the new version 4 of the software.  We're currently working with US and UK cyber-crime departments, who specialise in this sort of thing, and we're hopeful that we'll be able to track them down this time by using the accumulated evidence already held.    We are pretty certain that it's a continuation of the same attack last year, only at a reduced intensity to deter people from using the site "because it's terribly slow", rather than taking it down completely, and we're also sure of the motivations of those responsible.  Spite.   Please bear with us in the interim, and wish us luck in dealing with these.... "people".

Bien Hoa airbase 1966 - 1970

125 posts in this topic

I'd like to join with a diorama setting of a part of the U.S. Air Force base at Bien Hoa, South Vietnam in the late 1960's. I like to work in small scales and have a few aircraft that might look OK in a small diorama setting around 1966-68.
Bien_Hoa_1b_with_buildings_numbered_1024


The plan would be to, hopefully, scratchbuild some revetments, corrugated hangars and a tarmac/dispersal area for the aircraft. Incidently, in the colour image of the airbase, there is a fire truck in the top right and corner just approaching the revetments; plus a delivery type van at bottom centre. Does anyone have any details on these types of vehicles (or any other US vehicles typically found there), especially with plans, as I would like to add a few to the dio.

cheers
Mike

The van is a crew van, very popular on every air base at the time. Hasagawa makes one in 72nd scale.

You can also pick up some airbase stuff in scale from Shapeways.

The fire truck is probably an American LaFrance. Some good pics of Bien Hoa here:

Have you seen this build in 1/700 scale?

Very nice picture with a number of interesting types: F-100, F-5, A-1, C-47. C-130... and a number of drones beside the Hercules on the bottom left.

This sounds like a very interesting project, will watch with attention

Thanks Phil, some interesting stuff there. I've seen a F-104 Starfighter on there that I might get. I prefer kits though, rather than solid items; as with this Jolly Green Giant by Click2Detail which I bought last week. As to the fire trucks, I've seen an Oshkosh MB-5 which I could get and possibly convert to something similar.

Thanks Giorgio. There is so much detail on that photo that I have decided to do this all in 1:350 scale, mainly as I wouldn't be able to get most of it onto the dio in any larger scale. I've measured the area and it works out about 5 feet by 4 feet. I am just about to but a base coat onto a suitably sized piece of hardboard and then pencil on the various positions and access ways etc. I'll try to have enough of a start done by the weekend so that I can take some pictures.

The 1:350 aircraft that I have sourced so far are (actual desig numbers may not be correct): C-130 Hercules, C-47 Skytrain, A-4 Skyhawk, UH-2B Seasprite, H-34 Choctaw, UH-1 Iroquois, HH-3 Jolly Green Giant, AH-1 Skyraider, CH-47 Chinook, F-7 Crusader, P-2V Neptune and E-1B Tracer. I also have all the Tamiya and Trumpeter aircraft from the carrier sets: A-7 Corsair, F-4 Phantom, A-6 Intruder etc., so plenty of choice there.

I suppose you´ve already seen this: http://hyperscale.com/2007/features/runwaydioramadwa_1.htm. Great, isn´t it? Happy modelling! V-P

That's a lovely diorama V-P and I hadn't seen it before so thank you for posting the link. My idea is very similar but at 1:350 and covering a larger area. Whether I will achieve the same effects and weathering of that diorama is debatable but I shall certainly make an effort.

Another question:- Does anyone have any knowledge about the hangars in that photo of Bien Hoa, at the top? I am presuming that they would be to some sort of standard U.S. design for aircraft hangars but I'm not knowledgeable on that subject. If anyone can provide details or links then I would be grateful to hear about them.

Better get started so that I can show some pictures!

Thanks again

Mike

With much of the research work now done, although I am sure that I will still have loads of questions as I proceed; I have started to lay out the area of build. First thing was to print off the photo, which I have discussed in previous posts, and this can be seen at the back of the image below. The photo is made up of two A3 sheets. I then made a full-scale printout; which was achieved by using a view of the current location in Google Earth. The printout was scaled to 1:350 and printed onto A3 sized sheets; even with those large sheets it still took about 20 sheets that needed pasting together.

Here is the layout, positioned on the board that I shall be using. The area is just over 5 feet (1.52m) wide by 4 feet (1.22m) deep.

In the view below, I have attempted to orientate the layout with the photo. I have also added some information that has been taken from the photo and which will help me when identifying positions etc.

Bien_Hoa_1-350_GB_002_with_aircraft_posi

I don't have any 1:350 scale F-100 Super Sabre's (I seem to have everything else but!) although I am trying to scratchbuild some. If I am unsuccessful on the F-100's then I shall have to move the period back a little, in order that the aircraft I do have can look correct in this setting.

More to follow - hopefully!!

Thanks Phil,

The area that I am doing is, coincidently, the same area that was devastated by the B-57B explosion on 16 May 1965. It is mainly that catastrophe which prompted the building of the revetments that can be seen in the photo. The five 50,000 gallon bladders of JP-4 jet fuel, that were ignited in the explosions, are those situated behind the C-130 Hercules in the lower part of the image.

The hangars have long since gone so, there is no detail on Google Earth as to their size; however, looking at the photo's in your links would show the old corrugated one to be about 100 feet wide by 150 feet long and so I shall start constructing that one.

cheers

I want to start with some of the infrastructure so today I have started by cutting plastic sheet for the first hangar.

There are no measurements for this and so most of the detail I will have to rely on photo-interpretation.

Here, the basic components are cut out and assembly started; plus some of the aircraft and vehicle kits I have sourced so far.

The main building assembled. The roof and outbuildings, containing the offices and workshops, remain to be cut out and fitted.

Hangar has been primed.

The next stage will be to construct and fit the hangar roof and the side buildings. Once I've done them then I shall add more photo's.

Progress so far this weekend:

A second hangar has been constructed and these will be the two shown in the top centre of this PHOTO.
Out-buildings still need to be built down each side of both hangars, these contain the offices and workshops for the maintainers.
Bien_Hoa_1-350_GB_004b_two_hangars_800.j

The control tower is just out of view on the photo I referred to; it is situated next to the white buildings in the extreme top right corner, and it will be included in the diorama.
Here is a start on the tower complex, although it does appear to look like a village church at the moment!
Bien_Hoa_1-350_GB_005a_tower_started_800

Both hangars and the tower base have been primed. Some fiddly work now needed to make the tower glazing. It should look like THIS

I think that making the Revetments will probably take up most of my time, there are lots of them and they all need to be scratch built from ribbed plastic sheet.

First few revetments done and dry-fit positioned for first impressions

That's it for now, I going to push my eyes back into their sockets and give them a rest!

Thanks for looking and also for the encouraging responses.

This is a fantastic idea, great work so far!

I have a small suggestion to offer - from your presentation it looks like you're intending to lay out the base parallel to the board edges? I think it'll look a lot livelier and more natural if you rotate it a few degrees - more like an aerial photo or a view from a hill than a satellite image.

I realise this can create annoyances where you have to chop things off on the diagonal, but I reckon it'd be worth it. Your call though :)

Cheers,

Will

I agree with Will. Dios always look better when things are not quit parallel to the edges of the base.

Just a few degrees like Will mentioned makes a world of difference.

This looks fantastic and great progress so far. I concur regards the slight rotation of the layout; but yeah, your call.

I had considered introducing an angled perspective but whichever way I turned it meant losing hundreds of scale feet of the diorama - 100 feet at this scale is approx 3.5 inches (8.8cm). My other concern would be that there will be too much wasted area around those angled edges. As it is, the layout can go up to 8 feet wide but is restricted by the 4 feet depth.

The photo of the layout is taken from Google Earth as it is today; however, all those areas that look unused and wooded were in fact very busy squadron spaces and buildings which will be included in the dio. The long straight perimeter track, with the red line running through it, has a role to play for something a bit larger; and an angled layout would impact that area.

Keep the comments coming though; the base has not yet been set in stone (painted and marked out) so I may revisit the layout before committing to final presentation. At the moment I am busy cutting lots of tiny pieces of plastic for the buildings and revetments :blink::frantic:

That catastrophe started my interest in Bien Hoa as a diorama:

From Wikipedia:-

"Bien Hoa Disaster

This prompted more raids into North Vietnam. The B-57 mission continued to increase to the point that it became an around-the-clock commitment. This forced the weapons storage facility to deliver ordnance well ahead of the frag orders. There were bombs stored underneath the wings of the B-57s. The ordnance consisted of 250, 500 and 750-pound general purpose bombs, many armed with time-delay fuses (set for 24, 36, 48, 72 and 144-hour delays. All fuses were anti-withdrawal). There were also 750 lb of napalm stored on the ramp.

The pre-positioning of this ordnance was the basis for one of the "worst disasters in Air Force history". On 16 May 1965, while waiting to takeoff on a mission, a B-57B exploded on the ground at Bien Hoa AB. The B-57 was started with a black powder cartridge that fired when the pilot hit the starter switch, causing a small starter turbine to spin. These turbines sometimes spun loose and flew out of the starter housing. On this day, a loose turbine hit the fuse of an armed 500 lb bomb, setting off a whole chain of secondary explosions.[4]

Five 50,000 gallon bladders of JP-4 jet fuel went up in smoke. When the explosions finally ceased, ten B-57s, one Navy F-8 Crusader and fifteen A-1Es were destroyed plus several ground support units. Twenty-seven men killed and over 100 were wounded. The most severely wounded were evacuated to Clark AB."

As can be seen in the footage, that area had no blast protection at that time and that contributed in all the deaths, casualties and collateral damage. As a result of that, the revetments were built and is the location of the revetments in the photo link I posted.

In this drawing of the disaster (the red circles mark the fatalities), you can get the orientation of my layout from the position of the jet fuel pods which are on the upper right on this image and lower right (between the C-130 and the F-100's) on the Bien Hoa link I posted for my model base.

I have had another look at the layout and, based on recommendations, have rotated it by 10deg clockwise. It does cut out a fair section around some edges, however I will go with it; hopefully it will look better when finished.

The adjusted layout with the two hangars, control tower and some aircraft positioned for perspective.
