Touched by the rainbow

I was relieved to make my international to domestic connection, despite inbound delays, in Sydney this morning. 

Unfortunately, when we taxied out to take off something failed on the plane and we had to taxi back to the gate (where, eventually, we transferred onto another plane and I finally got to my destination about 2 hrs late). One bright spot (no pun intended) was seeing this rainbow as we headed back from the aborted take off. It was actually touching down among the buildings, but with the sunlight on the wingtip it looked like it could have been associated with that.
