The Canada goose was found by Jason Summers in January 1999. It consists of a glider pulling a tagalong.
At the time of its discovery, the Canada goose was the smallest known diagonal spaceship other than the glider, but this record has since been beaten, first by Orion 2, and more recently by the crab.
Modifications
It was discovered in January 1999 by Stephen Silver that Canada geese can be welded together by their wings, creating an extensible spaceship. Gabriel Nivasch, later that same month, reported that because the swan uses the same wing, swans and Canada geese can be welded together. He also found that a glider emulator can replace the glider at the front end of the Canada goose.
The crane has the same wing as well, so may also be welded.
