They probably don't know a ton more than the average MP, to be honest. But being on the committee they are exposed to a lot more of "us stuff" than they otherwise would be
We could have ordered a squadron of Cobra attack helicopters, had them built at Bell in Quebec - plenty of parts in common with the Griffons, added a lethal battlefield capability, increased our respect within NATO, and stimulated the Canadian aerospace industry. Heck they aren't even all that expensive!

But sssssshhhhh...we don't use the word 'attack helicopters.' We now use the term 'armed reconnaissance helicopters' instead of that scary A-word. (Much kinder, less scary)
Attack helicopters are mean, divisive, and have no purpose in a civilized future...and from what I am told, quite misogynistic as well...

This is the dude who cost Bell Canada the order of 15 Bell 412 helicopters the Philippines wanted to buy to help modernize their armed forces, because he wanted "firm assurances' they wouldn't be armed, wouldn't ever have door guns attached, or be used against the civilian population..."
They just rolled their eyes and canceled the contract, and bought Russian instead.
