Bernoulli Fan
Controller
But if he doesn't read back a hold short clearance can he clear the next aircraft for TO?
But yes, you are supposed to get "hold short instructions back" and he should have requested it after they didn't give it.
I haven't heard any clips besides the one posted by @RussVan , but based on that, the controller had already cleared JBU for takeoff and tried to get BWA to hold short when it appeared BWA was going to cross 22R without a clearance.
