I was on this flight as well, returning to MSP on Monday. They had to dump fuel to land, which was a bit of an odd experience. Did not think they would drop that much jet fuel over our 10,000 lakes! As a perk, they gave us a free sandwich and a coupon for miles or $10 of airport loot… Unloading and reboarding of the plane went fairly smooth too. Seeing all those fire trucks and knowing they were watching us was a bit unnerving, however. They did a nice job, all things considered.
