It worries me as a plastic engineer to see the mouldings over the exits lights on this aircraft all distorted by illumination heat from the exit light. It is only a matter of time before one of these dissolves into the exit light causing smoke at best and fire at worst.
Seeing this as an example of light weight polymer use worries me about the quality of other light weight panels you cannot see.
The Boeing Dreamliner the 787 was supposed to be the good as the best airplane of the world, now there's too much troubles with the 787s and the batteries, windshear cracks of cockpit, fuel leaky. Now they have to decide to reject and deny the 787 Dreamliner to be out of production because the Federal regulations have been in scrutuny and the FAA have failed. Citibank failed to comply to approve the Dreamliners for some airlines. Maybe next year, american Airlines have to decide to cancel all 42 of its Boeing 787-9s and Hainan Airlines also have to cancel those Boeing 787-8s and it consists of the dead airplanes that can't fly anymore and might be losing battle against the 747 programs and rival Airbus A350-XWB and the 737 programs.
