onomic maximum speed. Air transport,
careless whether the route be over land or sea, unhampered by foreign
frontiers, gives the Empire precisely those essential powers of direct,
supple, and speedy intercommunication which ship and rail have already
shown us to be vital.
Here again the geographical position of England presents a difficult
problem. England is divided from the rest of the Empire by a wide
expanse, either of ocean or foreign territory. Egypt, the starting-point
for air routes to India, Australia, and South Africa, may be described
as the centre of a circle of which England is on the circumference; and
it may be some years before an aeroplane can complete the journey
between England and Egypt with only Malta as a stopping-place.
The future of long-distance oceanic air routes may depend upon the
airship. Lighter-than-air craft, mainly for reasons of cost and
vulnerability, did not receive such an impetus from the war as did the
aeroplane, but the modern airship has claims for use over distances
exceeding 1,000 miles. It can fly by night with even greater ease than
by day; fog is no deterrent; engine trouble does not bring it down; and
it can take advantage of prevailing winds. It would reduce the sea
journey from England to Karachi from 22 to 5 days; from England to
Johannesburg from 21 to 7 days; and from England to Perth from 32 to
10-1/2 days. Its achievements have already been considerable. In
November, 1917, the German L.57 flew from Constantinople to East Africa
and back--a distance of 4,000 miles--in 96 hours; in June, 1919, the
R.34 flew from East Fortune to Danzig and back in 57 hours; and in July
it crossed the Atlantic, was moored out in America for four days, and
returned, a total distance of 8,000 miles, in the flying time of 108
hours for the outward and 75 hours for the homeward journey.
Before and during the war Germany gained wide experience in the design,
construction, and handling of airships. It is probable that as soon as
the peace terms and financial position permit she will begin to
establish this form of transport on a commercial basis. In accordance
with the Peace Treaty, and the Ultimatum of the London Conference of
1921, the construction of aircraft of all kinds is at present forbidden,
but Germany is fostering airship development by the means left at her
disposal. Her scientists are probing the constructional problems
connected with large airships, while efforts are being mad
