Found these very interesting, thought I'd share.

Interesting!

I assume most were taken by another person from the other cockpit.
Would like to know type of camera and how some were done?

Very cool photos. Those Bi=Planes must have been quite the sight for the residents of San Antonio. The article says a Kodak Vest Pocket Camera was probably used. Makes me wonder if the guys that trained here at Love Field in Dallas took photos like that.
