Don't aerospace companies take pains to prevent debris in their structures?  I
took a tour of McDonnel Douglas' aircraft assembly building in St Louis in the
mid-80s.  They were building AV-8B wings, and taking particular care not to get
x-acto knife blades or candy wrappers in the layers of composite material. 
They did ultrasonic scans of the wing skins to ensure no "de-bonds" or
inclusions occurred. 

What can we deduce from finding debris in the majority of these jets' fuel
tanks?  Sloppy manufacturing, followed by lax or non-existent QA?  Sabotage? 
Fuel with crud in it?
