I think Boeing. Incidently the first set of tires were so big that by
filling them with helium, save 150 pounds.

There were probably other more practical, if not political, reasons involved.
1) Why should Douglas have wasted resources on a plane the Air Corps did
not want? Boeing was just going into production of the B-17 at the time,
and even their plans for the B-29 were refused by the War Department
until 1940. Why should the War Department have even considered the B-19,
decidingly inferior to even the B-17, a necessary component to the Air
Corps? Why should Douglas have diverted its energies from production of
the DC-3, a money-maker, to the production of unwanted (and, ultimately,
useless) aircraft?
2) Strategic bombing was an unproven concept at the time. Even the B-17
was being produced originally for use as coastal defender. Any war plans
the War Department had for various adversaries did not include the use of
long-range bombers for purposes that would later develop. It was not
until 1940, when it appeared that Britain might be invaded or surrender,
that bids went out for bombers in the class of the B-29 and B-32. Certainly
no one knew in 1935 that the US would be in need of such aircraft half a
decade later. Also certain is the fact that the Air Corps had to fight
for every B-17 it could get. War Department appropriations were not
voluminous then. (Even Patton had to train his tank corps with cardboard
cutouts because the Army could not afford to purchase enough tanks.)

Douglas

(snip)
There aare time when one wished they could withdraw a posting, this is
one of them. B-19 was Douglass, but the remark about tire weight
stand. There was one other problem with hugh tires its footprint was
too small and there was as good posibility of breaking through some of
the runways. A picture of the B-19, makes the tire to be somewhere
between 6 to 7 feet in diameter.

It was later re-engined (from Wright R-3350 radials to allison V-3420
inlines) and redesignated XB-19A. After an extensive testing program
and some use as a large transport, it was retired to Davis-Monthan,
and scrapped in June 1949.

The B-19, actually XB-19 aka XBLR-2, was a Douglas one off like the
Boeing XB-15 to test doctrine and the construction of a long range
bomber force in the 1930s. Both the XB-15 and the XB-19 were very
large for their times and both were really underpowered, engine
technology hadn't caught up with the designer's ability to make heavy
aircraft. Neither was seriously considered for production, thank
god, and both were put into storage before the start of the war right
next to the crate that holds the various objects recovered by the
famous 30s adventurer Indiana Jones. Anyway Boeing came up with a
smaller and better design, the B-17 and latter the B-29. The rest is
as they say history (till Hollywood gets its hands on the story).

Evidently the B-19 , or at least the concept of it, got to Hollywood
first. In the Bugs Bunny cartoon where he's in a plane and the
Gremlins are tearing it up, the plane is supposed to be a B-19, and I
believe that the model plane shown at the beginning of those old news
reels that they show between movies on AMC is supposed to be
representative of one as well. In another Bugs Bunny cartoon, Bugs is
falling from a great height and extends his arms like wings and swoops
back up into the air, at which point he exclaims "Hey! I'm da B-19!!!"
: I've seen footage on _Wings_ of the B-19 landing after its first
: flight, and there was a very pronounced pitching up and down just
: before touchdown. The pilot seems to have deliberately, and quite
: roughly, yanked the yoke back and forth several times. Does anyone
: have any idea why that was done? That seems like a strange thing
: to do with a new airplane on its first flight, when its handling
: qualities hadn't been fully explored yet.

Kinda like the YF-22, eh ?

One of the original B-19 tires is still in the USAF museum at
Wright-Patterson. Gigantic...
Martin
The Douglas XB-19 was built as a "one-of" to explore the concept of a
very-long-range bomber. According to Fahey's gray book, it was ordered in
1937, delivered in 1941, 11 man crew, span 212 feet (which would have made
it I believe the largest warplane that had ever flown), 160,000 lb gross
wt, etc. It flew in June 1941. I don't think it was armed and I don';t
believe anybody thought it would ever fly in combat because it was powered
by four Wright R-3350 engines which were still experimental and
troublesome when the B-29 came on line.
With the size of the B-19, and the state of development of the engine, the
poor old thing could only move along at 204 mph. compared to 323 mph for
the B-17D that same year. There was a planned XB-19A with Allison
engines, never built.
As Erik Shilling pointed out, a major problem with the B-19 was its
gigantic tires, which put so much weight on the runway that its usefulness
was limited to highly developed airfields.
Curiously, the plane that evolved from all this--the YB-36--likewise was
delivered with two gigantic tires, maybe eight feet in diameter, one of
which can be seen at the Air Force Museum in Dayton Ohio. The YB-36 could
use only three runways in the United States and none I believe outside of
the country. In the production model, the super-tire was replaced by a
bogie, truck, whatever you call it.

The TPI indicator on the engineers panel is at the top along with the
aileron (sp), elevator and spoiler status.
Could TPI be for Tail Plane Incidence?
I was able to check a BOAC VC10 operations manual last night, it is
Tailplane Position Indicator. The VC10 uses a variable incidence
tailplane for pitch trimming and for take-off it has to be set to a value taken
from the manual based on weight and balance.
Hi, I am a RAF Flight Engineer Instructor on the Airmen Aircrew School
at RAF Cranwell.
I am ex C130 Hercules myself but some of my colleagues are ex VC10.
The answer is this...
TPI = Tail Plane Incidence
The indicator is on the Flight Engineers Panel
On the VC10 the whole tail plane is a moving flying control surface.
During the checks the Flight Eng checks that the tail plane is between
2 and 7 degrees.
Hope this helps
