That water would just tear them apart at top speed. Then of course, they are surrounded with steam. Lots of density to plow through without getting wrecked. So we now know it was filmed under powered flight for 2-3 minutes. Not the 10 minutes the planers proclaimed. Heck, 10 minutes would have been too slow for a plane at 35,000 feet and 600 mph. That is 60 miles in 10 minutes.
Sorry. Math mistake. That would be 100 miles traveled at 600 mph for 10 minutes. That is why we all need editors. Took me a while to realize the need for one, though.
