Hi Ron -

Amazing.

It only took an act of Congress to get NASA management
off its butt and doing what it should have been doing
years ago to ensure the safety of the people of this
country.

Congratulations.

You know how reluctant I am to bring this up here,
what with all the divorces and blown sales and
everything, but does JPL have any idea right now where
SW3's fragments are going to be in 2022? Of course,
they're small and slow, but they still might be quite
a nuisance then.

By the way, considering that NASA has yet to
straighten out its crater counts, in case you all need
an estimate as to what the impact hazard actually is
for operational purposes, my book Man and Impact in
the Americas is available for a mere $34.95 plus
shipping by calling either 1-877-494-0044 or
1-800-718-4514. In my opinion, several copies of it
would make a great addition to the JPL library. It
also makes a great gift for legislators - I know this
personally because it already has for some of them.
If you call the 800 number you can get personally
signed copies if you ask for them.

In closing, Ron, if you could please drop me a line
and let me know what NASA plans to do to carry out
their responsibilities under Brown. To promote book
sales I will be speaking to several hundred thousand
people on talk radio yet once again soon, and it might
be nice if I knew what NASA intends to do before then.

say hi to Don and everyone for me -
EP
off to powwow to recuperate
PS - I won't be making Beijing on 27 July either
