The Chairman It is my pleasing duty to-night to introduce Captain Tymms, whom youall know very well I cannot think of anyone who is better qualified to read thispaper than Captain Tymms, as not only is he a practical aviator, but he is alsoa member of the Air Survey Committee, who are the recognised authority on airsurvey matters in the British Empire

We are also very fortunate in having another member of the Air Survey Committeepresent in the person of Captain McCaw, the Secretary

I have received letters from Colonel Edwards, Colonel Crosthwait and WingCommander Laws regretting their inability to be present to-night

I now have much pleasure in calling upon Captain Tymms to read his paper CaptTYMMS Flying for air photography is essentially a matter of navigation If“navi-gation,” by its root, means no more than the moving of aship, it has come to imply the moving of a ship with precision to the placedesired

In opening the meeting the Chairman said Major Wylie requires no introductionfrom me He is a very old friend of mine, and when I was in charge of metalconstruction at the Air Ministry he was my right hand He is an engineer ofexceptional ability and has made many outstanding inventions Since the War hehas carried on his good work in the development of metal aircraft, and has alsoapplied the ideas derived from metal aircraft, to other engineeringconstructions

All developments of engineering in any one branch make improvements in otherbranches possible, for instance, the knowledge obtained from the construction ofaircraft has greatly improved automobiles, and, as Major Wylie is going to showyou to-night, it has greatly improved portable structures, not only foraircraft, but for other things I now have much pleasure in calling upon MajorWylie

The Chairman I feel that our lecturer to-night does not require a formalintroduction, for he is well known as the Honorary Solicitor of our InstitutionMr Wingfield has had very practical experience of aviation During the war he sawmuch service in the Royal Flying Corps and the Royal Air Force, and holds theMilitary Cross and the Distinguished Flying Cross Most of you have read, in theInstitution Journal, his interesting account of his experience in prison campand his escape therefrom

The subject of the law in relation to aircraft is of supreme importance toeveryone connected with aviation, and we shall listen to Mr Wingfield with verygreat interest I now have much pleasure in calling him to give us his paper
