EK and the UAE is far from 3rd world. They’re FAR more modern than any US or European carriers. maybe go see for yourself.
Just think of Elvis. I visited Graceland once while passing by Memphis...I didn't deliberately travel there. When you looked inside you saw what happens when white trash happens upon a lot of money.
That's the UAE to me.
Initial report says the plane slowed down during takeoff roll but it was too late to abort takeoff so they overran the runway.
