16. 26 February 1
I have in my files for 26 February 1966, Manchester, New
Hampshire. I do not seem to find a Bartlett, Ne Hampshire
case. See attached supplemental sheet A.
17. 1 17 July 1966, Centerville, Ohio.
Temporarily not
I have only the card on this case, but judging from ic there
seems to be a possibility that this one-witness case was caused
- by low-flying birds reflecting light. The sighting lasted 4 to
10 seconds, and witness mentions a high-pitched chirping noise.
E
I had a Sr - this case, much of it
