Most residents agreed that it could be an eagle, but it may have been Batman.
C.L. Fairbanks, 817 Logan, saw the bird and it was "about as big as a Piper Club airplane." It didn't have a motor and had retractable landing gear.
It disappeared eastward after a few moments of cir- cling the area.

Comment: Batman? I tell you newspapers get a little carried away sometimes! I guess they're referring to pterosaurs, which have been used as an explanation for such reports, as well as other pterodactyl-like stories from southern Africa, such as Kongamato. Of course, pterosaurs have been extinct for about 65 million years, and, needless to say, the idea of living pterosaurs is pretty unlikely. If anything, such reports probably refer to large bats and/or birds. The above account is probably of a large condor which was misidentified.
