maybe Boeing saved some money by sending some of the early P8 engineers to look around an MR2 on a visit to Pax River many moons ago. The crew were proud to show them around given how the UK would soon be equipped with the superior 4-engined MRA4....doh! The Boeing boffins seemed especially impressed with the sonobuoy launchers and how they used that little known power source of gravity to get the buoys gone!
