Pinging others to your post #28.
Hi Velveeta! :)
This thread has it all:
Manhole cover
tunnel
mystery chemical
explosives
airplanes
names you may or may not know

terrorist, think the name was Etheridge, a black panther?
It is all way too much to digest before the coffee is ready.
A good plot for a story. Or a jehad cell in Oklahoma.
