Airlander breaks up at mooring.
Of course the relevance of an FAA requirement for a british-registered airship under test in the UK is left as an exercise for the reader...

Thanks also to TURIN for belatedly adding his link; most interesting to read about the extraction and storage process.

In Airlander 10, helium lift is controlled much like in a conventional blimp, using multiple ballonets located fore and aft in each of the hulls. A ballonet is a gas volume that can be inflated with air inside the main helium volume of the airship’s hull. Inflating a ballonet with air increases the mass of the airship and compresses the helium into a smaller volume, with the net result of decreasing buoyant lift. Inflating only the fore or aft ballonet will make the bow or stern of the airship heavier and change the pitch of the airship. These operating principles are shown in the following diagrams of a blimp with two ballonets shown in blue.

What if animals were like Airlander. Go on have a laugh.

"We have paused for the time being collecting any payments in respect of the current fundraising and will be back in touch once we have determined our best course of action."
The damage assessment is expected to take "weeks" according to a spokesman.
From:- Airlander 10 'will be rebuilt' after collapsing at airfield.

The lighter side (sorry )
It was possibly a rather unfortunate piece of scheduling that, on the day of the incident, the "Yesterday" channel chose to repeat an episode dedicated to the development and success of the Airlander.
Personally, I hope the venture succeeds. Feel free to show any innovative developments in aviation that have been flawless from the onset.

... balloon rigid. I’m sure emergency deflation would require venting most, of not alll of the helium and air. I m sure there is no way of compressing it. Imagine the size and weight of the cylinders! I seem to recall from my visit that the cost of the helium to fill it is about £250,000. They reckoned to replace about 10% each year. 😢 I guess they may be covered by insurance.

The world's longest aircraft detached from its moorings and collapsed after a locking mechanism was not inserted correctly, a report has said.

Hybrid Air Vehicles Ltd are now overdue in filing their company accounts. I wouldn't have thought that they had made many sales or purchases this last year so perhaps they are thinking how best to issue a positive statement about the future. I still think that it is not an investment for orphans or widows.
