Have I been asleep for years or what.
These battery push backs have been around for at least 7 years I reckon.
These units clap onto the main gear, how about we say in the case of an A320 or a 737, behind No 1 engine and drive the main gear wheels to provide thrust.
During pushback, the engineer on the ground, via headsets, directs the pilot which way to steer so no need for steering pass pin.
When at the desired pushback stop the engineer, via remote control, commands the tug to disengage from the main gear, which it does and then powers it back to the bay.
The engineer then departs the A/C as per usual.
Simple.
And don't start me on the carry on baggage. It's a joke what is allowed to be taken on board these days.
