I was directing some videotaping with the 737 Ecco Demonstrator plane on our Boeing Field flightline this afternoon when one of the P-8As taxied in after a test flight. It was the first one I'd seen in person with its full complement of missiles under the wing. We were told it had been up doing flutter testing, hence the missiles mounted on the hard points. But it was definitely a bit of a bizarre sight to see this heavily armed 737 taxiing past the row of brightly painted commercial 737s on the line. A bit like seeing a Hell's Angel in full regalia at a junior prom.
