Crews in Nome, Alaska, were conducting search-and-rescue operations after the report of a missing Bering Air caravan with 10 people aboard.

On Jan. 29, an American Airlines passenger plane and an Army helicopter collided near Washington, D.C., killing 67 people in the deadliest air disaster in more than two decades. Just days later, a Medevac jet crashed into a busy neighborhood in Philadelphia, killing seven people and injuring over 20 others.
