The year is 1980: An SR-71 is traveling due west towards our coast returning from a reconnaissance mission over eastern Europe. It has been refueled in-flight to allow it to deliver its' valuable cargo directly to Vandenberg AFB in California. The plane carries on it's belly a module equipped with the latest surveillance electronics and optics. This new equipment allows the plane to capture perfectly details as small as newsprint from over thirteen miles in the sky. On this particular mission the module has captured valuable images, documenting our enemies missiles in various stages of assembly. 
As the plane approaches our coast a mechanical failure causes the module to drop from the plane. At the time of loss the plane is at the coordinates provided, traveling at exactly 750mph, at 70,000 feet over the earths surface. The module is coated with a top-secret material which not only renders it invisible to radar, but allows a frictionless fall to earth. The object continues moving west as it falls, until it impacts the earth in a remote area of West Newbury. It is never recovered.
Fast forward to 2004: Cutbacks in security in the former Soviet Union have allowed one of their warheads to fall into the hands of our new enemy. Unfortunately the Russian Government is unwilling to share weapon designs and specifications for fear it will compromise their own security. Recovery of the twenty four year old surveillance module is now imperative.
You have very little to go on. You know gravity is 32.2 ft/s/s. You also know that at the latitude of the drop, distance in miles is approximately equal to the change in longitude multiplied by 69.0941. (D=69.0941*(L1-L2)). You realize that sloppy calculations won't do. You’ll need to work in decimal degrees, rounding to no less than four decimal places in any calculations.
Good luck my friend. Your country depends on you.
