Gordon Bennett Balloon Race Aero Exhibition, Prague Coupe Deutsch de la Meurthe Paris Aero Salon : EDITORIAL COMMENT HE use of airship " R.33 " for the purpose of assisting the police to regulate the traffic to Epsom Downs on Derby Day was, so far as the work of the ship was concerned, an unqualified success. Reading the log of the day's work, it is quite manifest that the observer flying above the roads in a stable craft like " R.33 " is at an enormous advantage compared with the one who is endeavouring to straighten out a traffic tangle from Aircraft observations gathered on the ground. T> J0^ «s In the first case, the whole network of Road Traffic , . ' , -i r Control roads covering several square miles 01 country is spread out below, fully visible, and all the conditions of traffic existing at every point completely appreciable. In the other, no more than a few hundred yards of a single road can be seen, while conditions at other points have to be assumed. Naturally, mere observation of traffic conditions cannot help at all unless those conditions can be communicated to those below who are responsible for their regulation, and it, is here that the latest developments of wireless tele- graphy and telephony come to the rescue. A wireless station had been established for the day at the grand stand at Epsom, and with this station " R.33 " was able to keep in constant touch, greatly to the help of the police on traffic duty. For example, we find in the log an entry, dated 10.58 a.m., as follows : " Suggest part of congested traffic in Ewell be diverted at point 10 via Epsom College to racecourse." The answer was received : " Police proceeding to Ewell." Then, at 11.50 a.m., there is another entry : " Traffic is now moving from Ewell at point 10 to Epsom via College, and is affording immediate relief to the Surbiton and Wimbledon roads." It is quite clear that if it had not been for the information transmitted by " R.33 " the congestion at Ewell would have lasted for hours, since the police on the spot would have simply been able only to sort it out as best they could, and would not have been able to divert it via the College because they would have had no reason to think that the latter road was in any less congested a state than the rest. Only aerial observation, covering as it does a large area of roads, can be informative of
