This 60-centimeter natural color image of the "boneyard" at the Davis-Monthan Air Force Base in Tucson, Arizona, was collected by QuickBird on August 11, 2002. The boneyard serves as a holding place for out-of-rotation airplanes until their fate is decided; the dry, clear climate of Tucson provides an ideal environment for the storage of aircraft, as they can sit indefinitely without rusting. The hard, desert soil also makes for easy towing of the planes without the need for roads.

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Copyright: 1996 - 2024

    BSEE - KB3UON

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
