The pictures show the M29 Weasel rigged under a Douglas C-54 Skymaster. This was the only aircraft that carried and dropped an underslung Weasel. The C-54 had previous experience with carrying the M22 Locust Tank in this fashion, and even though the Locust was designed to be carried by the C-54, I don’t think it was very practical. The Weasel was easier to rig underneath the aircraft due to the lack of a turret. Broken down into parts, the Weasel still wouldn’t fit inside a C-47, but several were dropped from Fairchild C-82 Packets and many were landed by gliders. The underslung fast-drop snow vehicle was a concept from the 1930’s, and by the time someone actually got around to trying it the vehicles had grown in weight so much that their options were quite limited.

A request was made to Air Chief Marshall Harris for Lancasters, but he believed they were better utilized dropping bombs instead of tracked vehicles.

The Weasel was originally called the T-24, I’m not sure when the name was changed to M29. The M29C was the amphibious version, although the M29 would float enough to ford streams and calm waters.
