2008 Georgian spy plane shootdowns
It also claimed that white smoke trails such as seen behind the missile on the footage usually occur from land-to-air missile launches, and never with air-to-air missiles.
“This is not a full list of inconsistencies in the obviously edited video footage. [The footage does not give] a clear picture of when and where the video was recorded. If watched carefully, one can clearly see two roads parallel to the shoreline,” the Russian Foreign Ministry said. “But there aren't such roads in the indicated area of Abkhazia’s coast. Abkhazia's famous sand beaches - 100 meters in width - are not seen in the footage, even though they can be seen by satellite.”
Jackass-barque
A well-known example of a steel four-masted jackass-barque was the "California" (1890), the last and largest of the White Star sailing ships. The use of steel enabled the addition of another hundred feet to the two hundred foot effective maximum length of a wooden vessel. A fourth mast, called the jigger, provided the driving power for the increased length. The lower and topmast were built in one steel tubular piece. Mechanical improvements were introduced to the rigging.
