Martin 404 - N-145S Designed by Glenn Martin who established one of the first aircraft factories in 1909 (6 years after Wright’s first flight Martin produced: B-10 Bomber, B-29, Model 130(Pan Am) 404 was designed to replace the DC-3s having the same landing requirements, carried its own stairs, at 40 passengers almost double the number carried by the DC-3 (21 or 24), 100 mph faster Only 103 produced, 60 went to Eastern, The NAHM Martin is one of those; 40 went to TWA and 2 to the Coast Guard 303 proceeded the 404 but never became popular because of the glut of DC-3s (C-47s) being converted for commercial service Built in 1952, delivered to Eastern in 1952, served for 13 years. 1965 went to Southern Airlines, parked on a ramp in Ft. Lauderdale as few years later, owned by the bank we acquired it from in 1990 Thought to be one of only five Martin 404s in North America Lavatory is complete with skylight Seat placement is the way it was originally but the seats are much more modern that were added by the excursion company that once owned it NAHM did fly our Martin for several years but it became static in 2000 303 proceeded the 404 but never became popular because of the glut of DC-3s (C-47s) being converted for commercial service

As part of the NAHM's goal of acquiring significant propeller driven commercial airliners, a Martin 4O4 was on our list of desirable aircraft to find.  We also knew that this stalwart of 1950's "commuter" aircraft was getting to be almost an impossibility to find, so time was a critical factor.  When the opportunity presented itself to find one, we pounced upon it.

There were only 103 Martin 4O4's built.  Eastern Airlines had the largest fleet, 60 of them.  These Martins of Eastern Airlines were primarily deployed along their eastern seaboard routes, and in Florida.  TWA operated 40 of these planes.  Two went to the Coast Guard as VIP transports, and one was used as an electronics test bed.  Our Martin 4O4, serial number 14142, was delivered to Eastern Airlines in February, 1952.  It flew 13 years for Eastern, and in 1965 it went to Southern Airways, where they operated their 4O4s in the southern United States for a number of years.  After these many years of service, much the worse for wear, it was parked in storage.

An entrepreneur in Florida bought N145S, along with 2 other Martin 4O4s with the thought of using them to fly gamblers and vacationers to the Caribbean.  However, financial difficulties ultimately sunk this endeavor.

Now, with the bank owning N145S, it sat on the ramp in Fort Lauderdale, Florida awaiting its fate.  An alert NAHM member got wind of it.  After 18 months of back and forth negotiations with the bank, NAHM took possession of the Martin 4O4, along with the world's largest collection of spare Martin parts.  In 1993, the aircraft was in relatively good shape.  After some work and a paint job, "Skyliner Kansas City" is now one of only a handful of Martin 4O4s in existence.
