Stealth planes might be invisible to radars but they can do nothing against human eye, especially when they are contrailing.
Taken by Gian Luca Onnis, a (lucky) photographer and aviation enthusiast, on Jan. 25, 2013, the photographs in this post show a flight of six F-22 Raptors trailing two KC-135 and a KC-10 tankers overflying Sardinia island, Italy, on their way back to the U.S.
The six F-22 Raptors had deployed to Al Dhafra in the UAE via Moron, Spain, on Apr. 20, 2012.
Whereas the six stealthy planes of the 49th Fighter Wing returned to the CONUS (Continental U.S.) six F-22 belonging to the 3rd Fighter Wing, were flying in the opposite direction (via Lajes, Azores) to replace them in the Persian Gulf area.
Noteworthy, unlike the Holloman’s F-22As the 3rd FW’s Raptors from Joint Base Elmendorf-Richardson, in Alaska, are Block 3.1 planes capable to find and engage ground targets using the Synthetic Aperture Radar mapping and drop up to eight GBU-39 SDBs (Small Diameter Bombs) in the air-to-surface role.
