I had an observer on my second run. When I got back, I hit the rearm pad and then towered. From the tower, I saw his icon go flying across the ground (as described above). He was practically underground racing through town and could not end sortie for quite sometime. I believe he eventually Alt F4'd out.
Again, not sure based on above posts if that is a CM setup thing or if that is a bug but thought I should mention it.
