President of Ukraine's largest air carrier, Ukraine International Airlines (UIA), Yevhen Dykhne, says the Ukrainian Boeing 737-800 flight PS752 bound for Kyiv that crashed on Wednesday shortly after takeoff from Tehran airport was one of the UIA fleet's best aircraft with a reliable crew.

"On behalf of the airline team, I express our deepest condolences to the families of those who were on board. It was one of our best aircraft with an excellent and reliable crew ... We guarantee the flight performance of all our aircraft and our crews' high qualifications," he said at a press conference at Boryspil International Airport on January 8.
