How much did the runway conditions contribute to the Delta jet crash in Toronto?

According to veteran airline pilot Douglas Rice, runway conditions were a small but significant factor in the Delta jet crash in Toronto. The runway had compacted snow and ice, which likely affected landing conditions. However, airport officials had treated the runway in an attempt to maintain safety standards for continued landings. These efforts were intended to create a safe environment despite the winter weather challenges, suggesting that while weather played a role, it was just one of multiple factors that may have contributed to the incident.
