Rubbish
To gather relevant data this time (contrary to the test standards obviously not able to duplicate the issue and real in-service conditions)
What a load of crap, so fly the 787 180 Etops, it catches on fire and then its ok..
No the 787 should be Non ETOPS till they find the cause, if they cant then good bye to Li Ion baterries and redesign with proven Nicads and recertify the electrical system..
You cant let an aircraft fly ETOPS if it has a fault and you cant find the cause, thats just tombstone statistics to even try!
