Franklin Institute, Phila. Sept. 1932 and a book, 'Aircraft Engine' I can't read and I haven't been able to get it. Instruments (Chronograph) were been commonly used elsewhere in American planes but have not yet been adopted here. Part of the plane is at 1:30 p.m. a certain day, so I am to attend to it later. It is also possible that we will see pictures of another plane from which several men were killed and wounded in an attempt to repair damage caused by fire. The whole thing was very unfortunate for the crew. I believe there are many such accidents with planes every day, but they do not make headlines because they happen too often. There is a certain amount of danger involved in flying, especially when you're trying something new or pushing your limits. It's important to always follow safety protocols and be prepared for any situation that may arise during flight. I hope this helps! Let me know if you need more information about aviation history or specific events related to early aircraft development.
