This Air India crash is the first time a Boeing 787 aircraft has come down like this.
The model was launched 14 years ago and just six weeks ago the US planemaker lauded the fact the model, also known as the Dreamliner, has reached the milestone of carrying one billion passengers.
To mark that occasion the company said the global 787 fleet of more than 1,175 airplanes has flown nearly five million flights covering more than 30 million flight hours.
The crash is a blow for the company which has been struggling to overcome a range of problems, including fatal crashes, with its 737 programmes.
It will be another test for CEO Kelly Ortberg who is about to mark his first anniversary in the job.
He was brought in to try and help Boeing sort out the issues that were raising questions about its future.
We've had an update from Boeing - as a reminder, the plane that crashed is a Boeing 787-8 Dreamliner.
"We are aware of initial reports and are working to gather more information," the statement says.
Air India has set up a dedicated hotline for passengers. Families in India seeking more information can call 1800 5691 444.
UK Prime Minister Keir Starmer says his thoughts are with the passengers and families of those on the Air India flight that crashed in Ahmedabad on its way to London Gatwick.
He says: "The scenes emerging of a London-bound plane carrying many British nationals crashing in the Indian city of Ahmedabad are devastating.
"I am being kept updated as the situation develops, and my thoughts are with the passengers and their families at this deeply distressing time."
A senior police officer in Ahmedabad tells ANI news agency that the London-bound plane crashed into a doctors' hostel, an accommodation for local medical professionals.
He says police, firefighters and other civic workers reached the spot within minutes. Rescue operations are still under way.
