I had an interesting conversation with some groundstaff in Melbourne recently. At the time of the Ipad announcement they were told that their jobs were no longer required and would be made redundant from late this year. However, as a result of CASA requiring some additional legislation prior to the Ipad's operational use, these staff have been given "a stay of execution" until April next year.
We had a little chuckle at the timing. Plenty could happen between now and then.
