It sounds awful. So, did she and baby get back in the plane to fly home, or did you make a long drive? I was in the back of an old C-130A with a fouled air conditioning pack (so, lots of bad smells) on a hot day and we were lightly loaded and down low. Awful. I was self-conscious about getting airsick until I saw that everyone on that plane got sick: loadmaster, flight engineer, navigator, pilot, copilot (they were taking turns on the low-level flight training. . .whoever wasn't flying had a bag open or ready). Yep--it happens.
