I had a flight scheduled from WAW to KIV on LOT airlines. The boarding pass told they changed the aircraft to a 737 MAX. When I saw that I've immediately remembered that whole MCAS story from 2018.
The flight went okay, just normal turbulence here and there when passing the clouds, nothing new.
However during the descent right at the border between Romania and Moldova we've slowed down and decreased the descent rate. After that we went in a heavy pitch down (the heaviest in my life, and I've flown more than a hundred times) almost lifting us up from our seats. That's when I've started to be really worried as I've thought this was the MAX model based on the boarding pass. After ≈30 seconds of this pitch down increasing the pilots started to pitch up hard, causing ≈1.8g of acceleration. After returning the plane onto horizontal flight - we've continued the flight without anything super abnormal.
I really thought that was the MAX aircraft and prayed that the pilots were briefed on how to handle it's malfunction and we wouldn't have gone into the second cycle.
However after landing I've checked that it was actually a 737-800 and now I'm reeeeeeally curios what caused that behavior. Any ideas?
