They are doing well with the A330s - I saw them practising the tug and towbarless pushback off B23 in MEL the other day.
Heard a toot and looked up to see A330 + 2engineers wandering down the pushback line with tug (and attached towbar) stopped, tooting to get someones attention. Didn't look like a shear pin as all the parts of the bar were there, must remember to attach the towbar to the nose leg next time.
