For Boeing, the Paris Air Show has been a chance to listen to the industry, one Boeing executive says. "What do they think of us? It doesn’t matter what we think of us.”

Airbus secured more aircraft orders on Wednesday, raising its total to $21 billion at this week’s subdued Paris Air Show, while rival Boeing opted not to announce new sales following last week’s Air India 787 crash.

The show is happening at a delicate time for Boeing, which is coming off its best month for sales in a year and a half and a deadly plane crash in India involving one of its aircraft.
