One major point. At one point we are told:
"We found C-7 residue on UE-One earlier today, as the chief engineer was doing a final pre-flight warp engine test on the Warp Four engine system they just installed,"
As written, there's no real explanation as to the significance of this, or what C-7 residue is. It really needs to be explained in greater detail.
Just an educated guess, but C-4 is military explosives, so I'm assuming C-7 is, too, only a bigger Bang! for the same amount.
Finding residue on the ship mean there's probably a bomb hidden in United Earth One (the President's ship), as the residue is accidental transfer from when the saboteur planted the device.
