Goals of the 1st Smolensk Conference

• Create space for exchange of scientific results on 10.04.2010

• Create data basis for those who want to perform such research

Limiting factors

• No posibility of examining the wreckage and „black boxes”

• No access to reliable data

• Part of evidence irreversibly lost due to improper treatment

• No funding of such research is available in Poland

Positive elements

• In scientific community growing awareness of loopholes of the official investigation

• Growing number of scientists who openly declare their will of undertaking the examination

Examples of the difficulties we have...

17 m ?

Inconsistencies of the official reports

(need access to original data)

Radar altitude

120°

Issues that require laboratory examination

(first of all, bring the wreckage to our labs)

Data source files are needed and not low-quality plots of the official reports

Example: possible problem with engine 3 (not mentioned in the official reports)

The twin aircraft 102 is an important source of knowledge on technical details. Experience with servicing in Poland of former Soviet aircrafts shows that details of construction typically differ from the published technical documentation.

Polish authorities try to sell 102 to Russia, which expresses interest in this transaction...

Funding?

Standard paths of funding grants are here unavailable – the project is sensu stricto neither fundamental nor applied

Project proposal for National Center for Research & Development (NCBiR)
