This looks like the same sort of tape that Airservices Australia is currently using to patch up the Australian ATC system. (This material is also known by the term "Goodwill of ATC staff") Note well that by the end of this year, they will have run out of all available supplies of such tape and the new Minister, CEO and Board will have to try to spin their way out of the ensuing
PR disaster.
For myself, retirement will come soon enough...... but hopefully, not before the Minister devrees thant ASA offer an appropriate pay rise and maybe even retention bonus offers for the old farts approaching retirement, who constitute more than 20% of the total Aussie ATC staff numbers.
We'll see I guess.
I wish you all good luck.
