EAST HAVEN, Conn. (NBC) — Just before 11:30 a.m. on Friday, an airplane fell from the sky, crashing into two houses on Charter Oak Avenue in East Haven, not fat from Tweed-New Haven Airport.

Neighbors were jolted by the noise and noticed the fire and smoke.

Later, they would learn that the horrific accident they witnessed claimed the lives of two young East Haven girls, the pilot and his teenage son.

On Wednesday afternoon, police released the 911 calls those residents made.

Henningsgaard and his 17-year-old son, Maxwell, and two sisters who lived at one of the homes, Sade Brantley, 13, and Madisyn Mitchell, 1, were killed.

The girls' mother made it out safely.

The homes are scheduled for demolition, but it's not clear exactly when they will be torn down.
