we will never know if the accident could have been prevented had the controller said: runway 22 cleared for takeoff.
nor can we blame the controller...there are huge slangisms used by atc in america...so be careful.
I mentioned excellence as its own reward...management should try that too.
and I will say this as a general safety alert and concern. at any airport in the USA where construction is underway, ask for /demand PROGRESSIVE TAXI INSTRUCTIONS to the runway required by you the pilot. yes, I know most of us could figure it out ourselves, but I THINK YOU GET THE IDEA>
