Sara Humpal, 10, the youngest survivor of a plane crash Sunday at Yampa Valley Regional Airport, remained in serious condition Friday at Children's Hospital in Aurora, according to media relations specialist Elizabeth Whitehead.
The crash killed Sara's mother, Gaby Humpal, and the pilot, Hans Vandervlugt.
Sara's dad, Scott Humpal, posted on his Facebook page at about noon Friday that surgery on Sara's leg went well and that she won't be removed from a ventilator until a blockage in her lung can be cleared.
"When she hears my voice, she tries to get up off of the bed so I need to stay quiet and let her heal.....pray for my little angel...... thank you!" Humpal posted.
Scott Humpal and his sons Tad, 18, and Dillon, 13, also survived the crash and were released Tuesday from Yampa Valley Medical Center after they were treated for injuries ranging from broken bones to cervical instability.
Vandervlugt, 75, was flying Scott and Gaby Humpal and their three children from Corpus Christi, Texas, to Steamboat for a ski vacation when the Cessna 414A crashed 30 to 40 yards short of the runway at YVRA. An investigation is ongoing.
