On board Dreamliner with Boeing boss
The president of Boeing International, Shep Hill, has said that the new 787 Dreamliner is a "leap forward in innovation" despite problems with the batteries, which kept the aircraft grounded for three months.
Speaking from the Paris Air Show at Le Bourget, Mr Hill told the BBC that once the flying public get back on the 787 "they will realise the great potential it has".
Boeing is in a battle for a share of the market with competitors Airbus who have a new lightweight wide-body aircraft the Airbus A350.
