"The hull structure is, in general
principles, of standard type such as
used in Zeppelin arships and in
earlier British types, but a very con-
siderable saving Of structural weight
has been effected by large number of
| improvements In details"
This excerpt from the official British
description Of the ZR-2 seems to ex-
plain the disaster which befell the
| giant dirigible while on its trial trip
last Wednesday. The saving of struc-
tural weight was effected at the ex-
| pense of the entire airshlp and the
| lives Of 46 Of the men who manned
her. According to survivors, an alb
rupt change Of direction when the YES
sci was above Hull strained the frame
work beyond it's strength. 1t broke In
two In the middle and fell into the
| Humber river with terrific explosions.
Included in the dead were Commander
Louis H. Maxfield and Is more Of the
American crew which was to bring the
airship TO the United States, and
British Air Commodore l. NJ. Maitland
and % of the English crew. Only one
American, a rigger, was among the
survivors.
ZR-2 was the largest alrship ever
constructed and was built by the Brit
ish government for the United States
navy. The price was to be $4,000. 900.
or course, as she had not yet been
turned over to the Americans the
financial loss does not fall on the Amer
'ran government. The catastrophe was
not great surprise to those in Eng
'snd who had watched the building
and tests Of the airship. On several
! preliminary trials defects and weak
nesses were uncovered, and the final
trial flight which ended so disastrously
had been postponed repeatedly though
the weather seemed entirely favorable.
II Is said that enlisted men Of the
British air service stationed at How
den had offered TO bet ten TO one that
the dirigible never would get across
the htlantic; that they declared II was

NNws OF the disaster reached Wash
ington while congressional commit
tee was listening 10 arguments In
favor Of an appropriation for the COM
pletlon OF FRI, an Amerlcan-built
companion ship OF the ZR-2, on which
more than a million dollars already
has been expended. officers Of the
naval bureau Of aeronautics are conf
dent that the navy will he permitted
to continue It's rigid airshlp building
program Notwithstanding the loss Of
ZR-2.
Plans for the FRI call for an air
ship OF slightly smaller size than the
ZR-2, length Of go feet diameter
about 80 feet. and gas capacity OF APP
proxlmately 100000 cubic feet The
total cost Is estimated at S2,5O0.OOO
Her designers have adhered more
closely than the British to the struc-
tural plans Of the Germans, who were
the original builders Of rigid airships
The naval gas extracting plant at Fort
Worth already has stored enough
hellum gas to all the envelope Of
.ZR-1. Helium is far less dangerous
than hydrogen gas, being nonlnfiamma-

Late Wednesday night congress adj
journed for 30-day recess, or until
September 81. The senate finance
committee remains on the Job TO con-
tinue Its work on the permanent tar
if and the tax revision measures
