Without using FDR data as far as the barometric altimeter. I decided to work backwards from the impact point for further clarity that no matter how you slice it.. the aircraft was too high to hit the poles.
Pentagon impact ground elevation - 33'MSL
Light pole 1 elevation - 39'MSL
Light pole length - 40'
Total MSL height at pole - 79' MSL (top of light pole)
Total difference in height working backwards from impact to top of light pole 1 - 46' (79-33=46').
Distance to pole 1 - 1,036'
Speed - 781ft/sec at :44 (with speed trend 784ft/sec at :45 impact time)
Descent rate - 3980 fpm or 66 ft/sec
1,036/784 = 1.32 seconds
1.32 seconds*66ft/sec = 87.12 feet at that point in time.
Working backwards from the impact point based on descent rate of 3980 fpm
The aircraft was 87' above the impact point elevation. We need to be at 46' to hit the top of the pole as noted above.
Conclusion: Working backwards from the impact hole based on the elevations, speed and descent data, the aircraft is still too high to hit pole #1. 41 feet too high to be exact. 87-46 = 41.
Keep in mind this has nothing to do with the altimeter indication aside from descent rate. If the altimeter was lagging, the descent rate would be greater, therefore the aircraft would be even higher above the poles. We are basing the above information on elevation alone for height.
Once actual altimeter indications are introduced, we get a more accurate picture of how high above the poles the aircraft was.
Will be added to Pilots For Truth website in my signature.

because it seems too complicated to me
I'm not trying to be an ass or anything, but if it's too complicated for you (and it shouldn't be, if it is, your making it that way) then how is someone telling you what they think going to make it any better.
Your questions are not valid, because of several reasons, like missing/invalid/corrupt evidence, multiple cover ups, and other reasons.
We could solve a lot of these by Investigation, but when the government goes shell like a turtle, it's quite difficult.
Finally, what anyone personally believes, is not going to change anything.
