And it added to a spate of recent aviation accidents. On Jan. 29, an American Airlines regional jet and an Army helicopter collided over the Potomac River in Washington, D.C., leaving no survivors. On Feb. 17, a Delta Air Lines flight trying to land at Toronto Pearson International Airport amid strong winds and drifting snow crashed and flipped over on the tarmac; all 80 people who were aboard that plane survived.</p></div><aside aria-label="companion column" class="css-ew4tgv"></aside></div><div data-testid="RelatedLinksBlock-5"><div data-testid="lazy-loader"></div></div>
