I was an ART here at Dover when the C-5M came online. I was in OGV and I had a lot of conversations with the C-5 Flight Engineer who wrote quite a bit of the changes to the Dash 1. He told me that the new engines were producing so much bleed air, that they were blowing ducts out left and right because they could not handle the higher pressure/airflow.
