News Here, cant imagine Boeing will be to happy
It is worth keeping in mind that the FAA certified these 'firecrackers' with 240 min ETOPs out of the box. Absolute madness given all the new and unproven technology employed on this aircraft.
The electrical loads on this aircraft are huge (hence the Lithium batteries). That in itself causes me some concern. Electrical faults, as we have seen with this aircraft, are the greatest source of onboard fires.
Give me hydraulics and pneumatics any day.
