A member from the US Military chimes in:
Jonah:
I realize that most of these discussions have taken place in the TOS time period but I can’t beleive that YOU of all people could forget about the ALMIGHTY Q.
The Q forcefield (as seen in many first-season TNG episodes, including Encounter at Farpoint) travelled at WARP SPEED (Above warp 9.9, if I remember correctly) and it was able to completely encircle the Enterprise-D. Obviously a much more sophisticated forcefield than any mentioned in Jim Kirk’s logs.
