ATC Watcher I've been following the BFU releases but
At about the same time the crew of flight DHX611 started a descent as well. This happened without instruction from the radar controller. At the same time there was a statement on the radio that a TCAS descent was initiated. This transmission most probably came from DHX611
'At about the same time' is unacceptable. We have second-hand evidence on page 2 of this thread that it
was DHL who made the TCAS call. Is there or is there not an ATC tape ? Surely it's all on there, sequence, timing and everything. Why prolong the mystery ?
