== Balloon Jumps Across Country ==&lt;br /&gt;
[[File:daily-express-1927-03-01-p9-balloon-jumps-across-country.jpg|thumb|250px|right|[[Daily Express]] (1 march 1927, p. 9)]]&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;SIR A. CONAN DOYLE&amp;#039;S SUGGESTIONS.&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;AID TO PEDESTRIANS.&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
Tests with the first &amp;quot;jumping balloon&amp;quot; ever constructed in England, which are to be made by the &amp;quot;[[Daily Express]]&amp;quot; at Stag-lane Aerodrome, Edgware, at the end of the week, have aroused the interest of [[Sir Arthur Conan Doyle]].&lt;br /&gt;
&lt;br /&gt;
&amp;lt;q&amp;gt;&amp;quot;Some years ago,&amp;quot;&amp;lt;/q&amp;gt; writes [[Sir Arthur Conan Doyle|Sir Arthur]] in a letter to the &amp;quot;[[Daily Express]].&amp;quot; &amp;lt;q&amp;gt;&amp;quot;I &amp;quot;I conceived the idea of the use of small balloons or hydrogen knapsacks as an aid to the pedestrian. I never hoped to see it in practice.&amp;lt;/q&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;q&amp;gt;&amp;quot;There are, however, one or two conclusions which I reached, and they may be of some use. The chief was that too much should not be attempted.&amp;lt;/q&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;LIFTING POWER.&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;q&amp;gt;&amp;quot;If, as has been lately suggested, the margin between the man&amp;#039;s weight and the lifting power was only a few pounds, and if huge leaps were the result, it would mean a loss of control and be the cause of many accidents. What is needed is to turn the fifteen-stone man into a five-stone man, so that he can go on his way swiftly and without fatigue. Better thirty-foot strides under control than 100-yard springs where one may be the sport of puffs of wind or unseen obstacles.&amp;lt;/q&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;q&amp;gt;&amp;quot;It should not be necessary in such a case to release the hydrogen, and though, I presume, some safety valve must be provided to meet the expansion from changes of temperature, it should still be possible to make the one charge of hydrogen last for a considerable time.&amp;quot;&amp;lt;/q&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The &amp;quot;[[Daily Express]]&amp;quot; experiments will be as exhaustive as possible to test balloon jumping under various conditions. The &amp;quot;[[Daily Express]]&amp;quot; balloon is eighteen feet in diameter, and has a &amp;quot;lift&amp;quot; of something over ten stone.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
