These flight nurses deliver critical care in the skies every day, flying 24 hours shifts in a medevac chopper.
Now, their sisterhood in the sky is bringing them even closer through their shared journey to motherhood.
"When I found out Alex was pregnant, that same day I told her I was pregnant and we both started crying and a couple weeks later we found out Kendra and Michelle were pregnant," Sarah Imbrunone, flight nurse with University of Chicago Medicine Aeromedical Network, said.
Six nurses at the University of Chicago Aeromedical Network found themselves expecting at the same time.
"A couple of us were new moms for the first time and a few veterans flying through pregnancy and motherhood and so a lot of words of encouragement and leaning on each other when we needed the support," flight nurse Michelle Lambright said.
"I had a really rough time.. I had to stop flying at 29 weeks, but my partners picked up the slack. Thank God for them," flight nurse Kendra Johns said.
"The entire team outside of just us moms have been so supportive," flight nurse Juli Heiple said.
And now that they're almost all the way to the finish line, they'll continue to support each other through this next chapter.
"We always do a good job at checking in with each other," Caitlin Kilcoyne, flight nurse, said.
And be there for each other, no matter where life takes them.
"It's important to show a pregnant person working in an aircraft taking care of critical patients," Heiple said. "We can do hard things."
