Boeing intends to test the 777 fuel system?
And it is "expected" the fuel problem "will be" common across all other a/c operating in similar environment? The semantic problem isn't mine, sir.
You describe Boeing's "intention" to test the 777 fuel system. When will that happen? After another year?
Please look at your last sentence. This is not the verbiage of science.
"It's quite plausible that other a/c types will be affected?"(italics mine).
It sounds like a reporter with an agenda.
