You can do that in a car just as easily and effectively. Or a helium
ballon if being airborne is mandatory.

Or a garbage truck. Or an airport shuttle-bus. (Neither of which is inspected
in the literal sense; both of which are allowed to drive right up to the
terminal. [One out front, the other out back.] )

Or with a home-made RPV. (Think 'model airplane.' Now think BIG model
airplane.)

Using GPS and a solid-state autopilot the delivery error is about +/- 50m. At
about $20k a copy, with a 200 pound payload, 700 nm range and an average
service life of two trips, it's the cheapest way to fly dope since SAT.

Or so they say.

With regard to terrorists, the use of RPV'S (or their precursors) been in the
Threat Book since about 1996 (ie, since the availability of off-the-shelf
miniturized GPS receivers & autopilots... if this is news to you, check with
the model airplane builders).

The fact a potential threat has been defined doesn't mean anyone has paid any
attention. The use of kamikaze airliners went into the book sometime in the
sixties (it was already there, had been discussed -- and ruled 'not credible'
-- by the early 1970's)

As a point of interest, the WTC towers were designed to withstand the impact of
a fully fueled 707 -- the 'maximum credible threat' (aviation-wise) at the time
they were DESIGNED. By the time they were built the 747 was flying but nothing
was done to upgrade their structure to withstand the impact of a fully fueled
wide-body.

Most of the new 'Homeland Defense' crowd are bean counters. They'll do a fine
job making sure WTC doesn't happen again. Unfortunately, because they ARE bean
counters, the odds are about even money they'll be unprepared for the next
attack.
