the General Mills and perhaps by the Bureau of Standards in Washington.
The altitude control devices need to be analyzed for determination of optimum settings for initial action and rates of release of the ballast. This problem is awaiting some flights before a full scale, mathematical study is undertaken.
The main problem is the flight testing of the equipment planned as a tentative solution to the desired flight path. This awaits receipt of some large lightweight balloon envelopes and more of the altitude controls.
3. Limitations.
More work would have been accomplished had the equipment to be furnished by the Government arrived. The prefabricated building that is to be supplied by the Government according to the contract is urgently needed, as there is no housing available for the project at N. Y. U. The project personnel has been using work benches occupied by other projects. The project has been using the office space of another research group. This has not been satisfactory as six of their men and four of ours attempt to work in a joint laboratory and office 15 x 15.
Restriction on the project is the Civil Aeronautics Authority requirement that balloon flights be made only on days that are cloudless up to 20,000 feet. This is difficult to meet in the eastern United States but appears less difficult in the New Mexico area.
