Eyewitnesses have described the moment Air Canada flight AC8646 crashed into a fire truck on the runway of New York's LaGuardia airport, killing two pilots and injuring dozens of others. We were literally like 100 metres away, says 23-year-old Leo Medina, who was onboard another plane on the tarmac when the crash happened. It was like the plane got cut in half. He told the BBC he then had to return to the gate and had been waiting in the airport for more than 12 hours, sleeping on the floor on a bed of jackets. Passenger Rebecca Liquori, on the plane arriving from Montreal that crashed, described hearing a loud boom just after landing, explaining that turbulence during descent felt harsh. As we were descending, we hit a lot of turbulence, she said. Then we landed very roughly… Everyone felt it. She recounted how passengers helped each other escape the damaged plane. In the aftermath, LaGuardia airport has remained closed with numerous flights canceled or delayed, stirring fear among travelers amid the chaos from the collision.
