wLs: F-35 fighter jet development hampered by many flaws

A list of serious flaws has been found in a jet fighter in development for 15 years.

The F-35's ejector seat "failed to meet neck-injury criteria" and the jet had a "limited ability to respond to threats", the US defence department has said.
The jet's development, by Lockheed Martin, has already cost $1 trillion (£0.7tn), partly funded by the UK.
Previously, its UK planned deployment date was put back from 2012 to 2023.
"It's one of the most delayed and problematic fighter programmes in history," said Justin Bronk, a military analyst at the Royal United Services Institute (RUSI).
"If this sort of news keeps coming out in terms of continued problems with the testing... it's potentially embarrassing," he told the BBC.
Mr Bronk said that while the aircraft could be deployed in its current state, pilots would not be able to fly with as much freedom as planned because of the many technical limitations.
But he added: "They will make this thing work because they have no choice, there's no alternative.
