Caitlyn Jenner is mourning the loss of a close friend.
On Wednesday, the reality star took to Instagram, sharing a brief eulogy to Charles T. Aaron, who died recently died in a motorcycle accident.
“Sad day yesterday. My good friend Charles lost his life on Sunday,” Jenner captioned the picture collage. “My prayers go out to his father @chuckpaaron who lost his best friend.”
Jenner’s photo consist of three different pictures in a collage, feature different moments from Charles’ memorial service.
Charles, a helicopter pilot, was sent off in his “last flight,” as his father – a longtime flight instructor to many – took to the skies in a helicopter, with a small pod of other choppers during the funeral.
“My son’s last flight (here on earth). He was such a gentle giant AND my best friend! I love you Charles!” Chuck captioned a video of the event. “You will be in my thoughts everyday for the rest of my life. I was so proud of you!”
In an Instagram post on Monday, Charles’ father also honored his son, calling him the “Sweetest, kindest, most honorable and gentle man you could ever want to meet.”
“We worked everyday together, we flew all over the U.S. Together in a helicopter,” he wrote.
