Can't quite see from that picture but the bottom of the engine nacelles look very close to the tarmac?

Doesn't look quite as bad in this pic. Apparently happened on a remote stand while being loaded for a freighter flight.

From reading the title I expected to see a tow bar and a tug having exercised the old "push back with the park brake on" chestnut but no, it looks like it just collapsed.

Short video from Twitter - mentions 'no injuries', thank goodness!

‘Dreamliner’ nope, nightmareliner more like it. It’s really a very poorly designed and manufactured aircraft, in my opinion.

Engineers working on a gear issue. Didn’t put the gear pins in the correct place.

Allegedly.

In some of the photos you can see engineering carts but they are labelled A380..

It happened to a 747 when I worked there. Shame I didn’t have a camera on me to get a photo of it.

Someone on PPrune is saying his friend was the despatcher for this flight, she was onboard in the forward cabin talking to the Captain, FO was in the flight deck when it happened. No warning, they were thrown to the floor, sounds like no injuries fortunately.

Rumour is the locking pin could have been in the wrong hole whilst maintenance was carried out, as described in this proposed Air Worthiness Directive

New B787 aircraft arrived for post-delivery mod. The NLG drag brace pivot link hollow bolt will accept the gear pin snuggly from LH side while the correct locking hole is 3 inches away and "unmarked." An inexperienced mechanic could accidentally place the locking pin in the wrong hole leading to gear collapse during ground testing damaging the aircraft and potentially injuring or killing persons in the vicinity of the gear.
Apply sealant or similar mitigation to the LH inside bolt hole, mark correct hole with red outline. Has previous Engineering Authorization been implemented on the fleet?

I've never worked anywhere that would allow a design like that to be made. If you can put something in the wrong hole, change the design so that you can't. Poke Yoke 101

Unfortunately it is increasingly looking like the cause
