With a max pressure diff of 7.5psi trying to push 200-odd square inches of centre window OUT, maybe not!
Ummmm, so at 5 miles, 1500 feet, with about 0.1 PSI diff and 246 knots there is how much pressure on that window?
Mabey the windows not the weakest link, but i dont think your reason is the one why (if that make's sense).
