So there I was minding my own business in 1D on BA1311 in ABZ when I noticed a small Eastern Airways propeller plane at the next gate (Possibly a Saab 340) getting ready to go.

What I had not seen before, however was the plane reversing back under its own power with no push-back truck, before heading out to the southerly runway ahead of our A320.

I did not realise planes could reverse (even propeller driven ones!).
