I’ve seen this happen with the trains in the Atlanta airport, which doors do not bounce back when obstructed.
The kids are always taken care of until the distraught parents get back.
Wow, I was about to post a reply that the same thing happened to my wife and 6 year old son at the Atlanta Airport!
I guess it must happen a lot there! I was beside myself and tried to break the doors down to get him. Luckily, there was a security guard right there and brought him on the next train.
Weird how all is fine one second and you turn into a caged lion the next. I never saw that in myself before.
