This from Asher Heimermann:

As of April 2020, Flight For Life no longer operates out of McHenry. Air Methods has taken over the McHenry base, which is located at Northwestern Medicine McHenry Hospital. As of this week, the helicopter appearance remains largely unchanged besides the removal of the Flight for Life text which has been replaced with LifeNet.

Flight for Life also closed their Fond du Lac, Wisconsin base in January 2019. The organization now operates just one helicopter out of the Waukesha County Airport.
