Dear Friends:

A few short years ago we created this message box on our home page, asking for your help to keep this site up and running. In that time, many of you have generously donated to our PayPal account and we are forever grateful. With your help, we've been able to make the necessary upgrades to our server to keep the site running more smoothly than ever!

The meager ad revenue generated by this site isn't sufficient to cover the annual cost of running the server, and we who manage it have never made money from it.

In an effort to continue serving the needs of aviation enthusiasts around the world, we continue to ask for donations to keep this site up and running. If you're still enjoying this website and would like to help us continue being the BEST site on the Internet for your aviation screenshot needs, please consider donating.

Thank you,
Tobin & Rush

Keystone B-4

The Keystone twin engine biplane bomber are a American family of closely related bomber designs based on a large, single-bay, conventional biplane with engines mounted in nacelles on the lower wing. Depending the variant, the tail could be a single one or twin tails and even a triple-finned tail for some LB-5.
They were used as Light Bomber (LB-5 and LB-6) or as Bomber (-3 to -6) between 1927 and the mid-thirties.

The whole production reached 194 airframes for 6 different types and their subtypes/working models.
