I was aboard Southwest Flt. 260 MDW-DTW last week. We landed on Runway 21 R and the pilot slammed on the breaks. When we came to the intersection of 27R/9L the pilot suddenly turned the plane to the right half of the runway and then swung the aircraft into a complete 180 to the left. we were now turned around and were headed in the direction we just came in on.(keep in mind, this was all on the active runway) He then turned an immediate left onto the first taxi (shown on map) and then to gate A9 in the Berry Terminal.
I have never ever encountered a procedure like this before in all my years of flying. I thought this was quite dangerous especially with aircraft on final behind us (I dont know how large the spacing was).
Has anyone ever had this happen to them before?
