Heard our first mayday in progress flying over Oklahoma yesterday around 3:10pm. N4386N. Lost the entire engine and you heard the engine alarms going off. They had also apparently lost pressurizations and then heard the engine caught on fire. We had to switch atc a few minutes later so didn’t hear the resolution. I know the pilot was pretty calm for what was happening and ATc was trying to get him down to 17k (airport). Hope the two made it down safely but I haven’t seen any mention anywhere yet.
