Brazilian Air Force just released the first images from the Legacy
Judge by yourself:

For me it looks very unlikely that the Legacy is responsible for the 737 crash, unless a 100cm piece of winglet is enought to bring it down.
I guess that this images and the lack of distress call from the Gol crew points to a very sudden problem with the Boeing..
Food for thought, for sure
