I was on BA193 arriving into DFW on April 21st.

Once we had landed someone from the flight deck apologized and said "We have been told by the company here that due to the way the aircraft was loaded we have remove one pallet of freight from the back before we let anyone off at Dallas. This is to avoid the aircraft being too tail-heavy and is for your safety"

That is the first time I have heard that announcement. In my head I had images of people getting off the plane and then the front wheels lifting up (like when one person gets off a see-saw).
