Before asking Gp/Capt Liptrot to give us his lecture a few words of introduction may not be out of place It would be difficult to think of anyone better qualified to talk on the subject of rotary wing history than Gp/Capt Liptrot, as he has been intimately associated with the development of this type of aircraft for the past 20 years, and latterly in his official capacity at the Air Ministry, Ministry of Aircraft Production, and Ministry of Supply It is probably correct to say that he has had inside knowledge of every project m this country as well as a good many abroad

Gp/Capt Liptrot is a member of our Association and his enthusiasm for rotary wing flight has shown itself in a practical way during the past two years during which time he has done quite a lot of solo flying on the R 4 helicopter
