Ann Arbor unidentified aerial event — November 20, 1957

We did not see the Sputnik, because it passed over earlier than the predicted time, but I was rather startled to observe a stellar-like object, which appeared in the northeast at an altitude of about 30° and moved very rapidly, in about three or four seconds, in a rather flat trajectory across the sky before it disappeared almost directly in the west. My friend insisted that it ought to be reported and hence I did.
