I also doubt it is terrorism unless those kooks have become exceedingly advanced. The whole incident is obviously something that would make terrorists happy, and where it broke up (Palestine, Texas) could be viewed as symbolic due to the presence of an Israeli onboard, however all that is coincidence (for any terrorist to plan an attack so that the shuttle breaks up over a place called Palestine Texas would require such advanced tech that they would not bother with such an attack).
Hence i do not think it is terrorism, and if you check the picture i posted on that other thread you will notice that a piece of insulation broke off during launch, and maybe that led to this disaster.
Take care and God bless.
Perhaps not terrorism, but IMHO, it would be wise to specifically investigate space based weapon systems by other nations which might have been able to target the shutle in that vicinity.
I'd consider any evidence of energy flux or directed energy emissions in a specific freq over a wide spectrum within line of sight of the trajectory of the shuttle prior to its breakup.
There were conspiracy theories regarding the Challenger explosion attributable to the rockets being lazed upon launch via a space based system as a warning.
Odds at present would be for any hazardous mishap to be the root cause.
Anybody hear any live conversation with the shuttle immediately prior to the loss of signal?
