Manhattan would be easily blown, remotely. Place a time-charge beneath a car at the head each principal subway line (which commence in other boroughs), set to blow at the main stations.
For the West Side, supplement with a charge in the PATH train from Jersey.
For the East Side, supplement with another in the LI Railroad from the Island.
Also Metronorth coming into Grand Central on 42nd st.., But: Most subways are underground in Manhattan. A device that gives off enough bang to be felt above ground has to be at least as big as a suitcase. How likely is a suitcase unaccompanied by a human to go unnoticed on NYC subway? Not very. Under a bus seat? A little less noticeable. A smaller timed device would be limited to blowing up or gassing or incinerating only whoever's on the subway - and the worthy victims don't take the subway. I think a parked car (or a car driven by a suicidal driver) is more likely for delivering a suitcase or larger.
Forget anything above 86th Street, they'll applaud; like the WVA and VA hillfolks will hooray the destruction of see-navel DC and its high-pitch babbling wonks.
I object to any terrorist plans that don't include the complete destruction of Columbia University and the City College too. :-) --- Dr.Dimitri Vulis KOTM Brighton Beach Boardwalk BBS, Forest Hills, N.Y.: +1-718-261-2013, 14.4Kbps
