Talking To Explosive Demolition Experts....Suggestions?

Ok, so I've sent a few e-mails to some demolition companies asking for interviews via e-mail or the telephone. No response yet so I'm planning on cold-calling starting tomorrow. I've gathered a list of US and foreign companies that I found specialize in 'explosive demolition'.
Like most of us, my time is short and valuable...so I want to ask for suggestions on how to handle this and come out with some definitive expert opinions on the demolition of WTC 7.
What do you guys think would be the best way to approach experts in the field of explosive demolition about WTC 7? If you think certain questions would be valuable...please share.
My idea...
Provide the interviewee with the various videos of the demolition of WTC 7. I'll put this on my website www.boldwater.net as not to even bring the idea of 9/11 into the picture.
I have them watch the video and maybe just ask them to write a paper/email explaining their impression. Maybe I don't even need to ask questions huh? Just say "please share your thoughts on the destruction of this building".
I will...
1. only make reference to the 'Salomon Brothers Building'
2. not mention 9/11, wtc 1, 2,7, demolition, explosives, fires, etc.
I'm hoping the footage does not give away the fact that they are looking at NYC on 9/11/2001.
i'd be curious to find out
how many people in that business have NOT heard about WTC7... i think your approach should depend on whether or not they already know the bakground... "tricking"them like Jowenko was into commenting on it out of context is grerat if they are unaware of it already. If they ARE, then you might ask them for their opinion as to what is taking the govt so long to come up with the explanation--like, in their expert opinion, what is so mysterious about the collapse, if as we have been assured it was definitely NOT CD?
oh and if you want to be uber sneaky
call pretending to be a would be debunker who is frustrated by all these crazy conspiracy theories and you thought that THEY of all people could help you explain to the kooks why it is clearly not a controlled demolition... any number of ways to be dishonest about this... :) can you tell I worked in advertising for 3 months? that's all you need to learn to be a real bastard!
Ask them how much time and
Ask them how much time and manpower it would take to set up for a demolition of this size and if there's any way it could be done behind everyone's back.
