Chicago area on either of these dates, or if some other adver-
tising planes that you know of, wer area at the time
would be helpful in our investigation. The inclosed self- -
addressed envelope is your convenie nce in replyinz.

She said it had to be over Pal-Waukee o or Chicago and asked if we could see it.
I could see the object she was speak was
directly over the city of Chicago.
I am familiar with aircraft displaying landing lights. The lights ar pronounced
and the aircraft is ot really visible. From the second floor of the Administration
Building at the Pal-Waukee Airport, the object looked like it was between
3,000 to 5,000 feet directly over the Chicago Loop or to an area one or two miles
inland. It had an outline about one and one half times as large as if looking at
an aircraft with lights on. The lights were within the confines of this outline
