The numbers really do not add up for aircraft to to have not been delivered - that is a massive amount of stock to be holding, but it might be true.

I also think in the last hearing it was said that aircraft were delivered.

This from Tom.

In June, FAA safety engineer Thomas Thorson, concerned that his agency was hurriedly approving Boeing’s desired changes, formally objected.

“I do not agree that delivery schedules should influence our safety decisions and areas of safety critical findings, nor is this consistent with our safety principles,” Thorson wrote, adding the agency’s technical experts had discovered errors in the way Boeing summed up the various risks of the lightning protection features and that with the removal of the foil “the fuel tank ignition threat … cannot be shown extremely improbable”.

Thorson estimated that if the methodology was corrected, the ignition risk “would be classified as potentially unsafe”
