I cant verify the 7135 number but it felt like we went downhill very fast. I can however verify that the on board map showed us going from 40000 to 32000 in just a couple of minutes. Pilots made no announcements. The flight was DAL138 DTW AMS departed Detroit 31/12/14. I'm just curious - thought at the time perhaps there was some military activity which entailed us getting down fast. airspeed also went up very quickly and that does tally with flight radar track log.
It was an eventful trip - we started out of CUN the same day and had a 'no flaps' landing at DTW with full blue light services in attendance.
