A Philadelphia father is calling his son a “superhero” for shielding his younger sister when a medevac jet crashed in a Philadelphia neighborhood, showering flames and debris on homes and the vehicle in which the family was riding.

The number of people injured has increased from 22 to 24 after a medical jet crashed into the ground in Northeast Philadelphia, officials said. The death toll remains at seven.The number of wounded went up because there was a firefighter who had a heart attack and a police officer who suffered smoke inhalation in the incident,

The impact area where a medical plane crashed in Philadelphia was notably “expansive,” U.S. Transportation Secretary Sean Duffy said Monday after viewing the site.
