I expect someone has already “done the math” on this, but...
My husband’s PhD is in Physics/Adaptive Optics and was in charge of the mega telescope at a space surveillance site. He checked out the photos of the telescope in Trump’s penthouse and identified the size, make, etc. He did some calculations and said that with a line of sight to the WTC, the jumpers could’ve been seen — easily and clearly.
I cannot understand why the people in our own party are so vicious when it comes to Trump. I can’t understand why they’d rather see Hillary as president than Trump, but that’s exactly the mindset.
Your husband should let the Trump campaign know about his calculations.
