[AGL] Joe Stack flew his plane into the IBM building

[Michael Eisenstadt]

We had occasion to drive by the burnt out office building this morning
twice.
The first view was at medium distance we being on the highway. Coming
back we were on the access road. I couldnt see it but passenger wife could
we both smelt the ashes a few moments later in a sealed airconditioned
car. Wow!

Looks like he aimed for the base of the building judging from the visible
gouge in the earth or in hitting a moving car his plane was deflected higher
than he actually aimed himself at.  The NTSB report in a few months may
or may not touch on this possiblilty.
