If you only saw the tow bar being disconnected, note what the right wing does to the lighting tower.

Aaahh, your worst nightmare when towing your boat behind your car.
But a boat doesn’t have a brake rider. What was he thinking?

Good old-fashioned decapitation.

I flew in Angola for a fair period, this is not unusual.

True, it happened at Porto, in Portugal.

To an Angolan airliner.

Yes agreed, but this will be all down to the handling/engineering agents, would be surprised if any airline personnel were involved.

Sooooo, what happened here? The tug has disconnected, but the aircraft is taxiing with the tow-bar still connected? (no beacon showing).

Or the brakes were not set and the aircraft rolled forward out of control, with nobody on the flight deck?

If the aircraft had been towed to a remote stand, why were no chocks set before disconnecting the tug?

Nobody on a headset that I can see.

Seeing how the towbar is still connected to the nosegear, I would guess that the towbar came adrift from the tug. It looks like the tug driver momentarily thinks about 'reconnecting' with the aircraft, only to think better of it and scarper off to the left side.
Perhaps the bar wasn't connected properly to the tug, or perhaps the bar failed at the tug end.
Fun to watch though - especially as no animals were hurt during the making of that short movie...

It's not just our African friends who make mistakes. Back in 2012 an EAT(DHL) A300/600 freighter started to taxi at East Midlands after the tow bar had been disconnected but before the tug had moved out of the way. The tug, one of the really big ones that can push anything, was completely turned round and impacted the side of the aircraft fuselage. Fortunately the ground crew all escaped injury.

Basically was this:
The T7 had apu inop and no hyds and no brakes (no beacon on)
Two engineers inside...tried to brake but with no success at all.
Plane was being towed to spend the day till next evening return flt to Luanda.
After first pushback/towing segment the tractor/driver needed to change the tractor from "push" to "pull" doing the normal 180 off the plane for a few moments.
During this 180 manouver, and the T7 without apu and hyds, someone seems to forget to put some chocks during the tug/tractor removal for the 180 manouver.
And then here it goes.
By miracle it didn't hit a parked White Vip 319. One light pole hit by right wing.

Does the 777 not have a brake accumulator? Would it not have been prudent to have an engine running with an inop APU?

There are now some updates refering all chocks were poperly put on place and time, but during the first seconds of "pull" already on its way to the final resting stand, the towbar simply broke without any fault from driver or ground team at all.

As Check Airman asks: surely there must be a brake accumulator and a battery driven electric hydraulic pump for the parking brake, at least?

I don’t know the B777 systems, can anybody comment?

Brake accumulator YES, but no elec DC pump for brake system/accu.

Brake system accumulator supposedly allows approximately 6 brake applications when fully charged. Surely when towing an aircraft "deadship" one would supply EXT PWR and charge the brake system accumulator first BEFORE carrying out said towing operation. Am I missing something here?
