Frank Sinatra had a very nice M404 for his personal use. We had to decide on a paint scheme. The Martin 404 cruises at 240 kt, 85 kt faster than the DC-3. The success of the 240 led to the 1.37m (4ft 6in) stretched 340, which first flew on October 5 1951, and the improved 440 Metropolitan which incorporated extra cabin sound-proofing, new rectangular exhaust outlets, tighter engine cowlings, and some other aerodynamic improvements and first flew on October 6 1955. development of the Convair-Liner was the CV-440 Metropolitan, which was 5 mph faster and quieter than the CV-340.

Many of the Convairs were also built for the US Air Force as the C-131 and T-29 in many versions, and for the US Navy as the R4Y which were redesignated too as C-131 in 1962.

Fuel capacity is 1,000 gallons in each of the two wing tanks. Whitesell's goal is to collect, preserve, and keep flying as many piston airliners as possible.

Only a few, however, are passionate about piston-powered airliners. The flight was a puddle jumper from. WebA few facts about the Convairs: The CV-340 had a maximum takeoff weight of 47,000 lb and this was raised to 48,000 lb on the 440 when using 100 octane fuel, and 49,100 lb and even a bit more with higher octane and the full 2500 hp of the CB-17 engine.

It coughs, belches, and stirs to life one or two cylinders at a time, all the while spewing great clouds of exhaust (and, of course, oil). The first DC-3 built was the Douglas Sleeper Transport, a 14-bed sleeper, also known as Skysleepers by airlines.

While more economical and faster than the Martins, the sleek 19-passenger aircraft were often plagued by engine troubles and many passengers disliked the cramped cabin. The Glenn L. Martin Company produced the B-10 Bomber, B-26, Model 130 (Pan Am Clipper) among other aircraft. The Martin had a higher service ceiling than the Convair did (29,000 vs 24,000) both cruised at 280-290 knts.

Though reduced in numbers by attrition, various forms of the "Convairliners" continue to fly in the 21st century.

After aborted negotiations with TWA and Eastern for "Super 240" orders, Convair temporarily halted 240 series production.

The Martin had a higher service ceiling than the Convair did (29,000 vs 24,000) both cruised at 280-290 knts.

The Convair Model 37 was to have a wing span of 230 feet, 182 feet in length, and a double-deck fuselage.

N636X is now the flagship of Airliners of America, a nonprofit organization in Camarillo, California, that was founded by Whitesell. Randy Dettmer, a general aviation pilot and architect, who met Whitesell at an airshow and "got hooked by his infectious enthusiasm," said, "I also flew in these old piston airliners when I was a kid.

Even though it does not have a mach-meter as such, this is indicated by the reduced IAS allowed above 10,000 / 13,000 ft. To be fair, the only time this was likely to be a problem was in Winter in the Northern parts of North America and Europe. The cost is $1,500 (tax-deductible). Swearingen Metroliner turboprops began to replace the Martinsin1977.

The first such conversion flew on January 19 1960, although it was not until June 1964 that a converted aircraft entered service.

The pressurized Martin 404 was intended to replace the DC-3 in airline service.

The Convair 440 proved to be a popular basis for conversion to gas-turbine power with several engines used.

The Martin 202 competed with the successful Convair 240.

Design of the original 110 was initiated in response to an American Airlines request for a DC-3 replacement. Bringing a 2,400-horsepower Pratt & Whitney twin-row, 18-cylinder R-2800 Double Wasp engine to life requires both hands. Fuel capacity is 1,000 gallons in each of the two wing tanks.

Thus converted 240s became 600s, while 340s and 440s became 640s.

Five were qualifying in the Martin for the first time.

Externally, a 440 can be identified by rectangular exhaust stacks and in some cases an elongated nose, originally conceived to house early weather radar, though this is not necessary today. It was also available with twin Pratt & Whitneys that produced 2,500 hp at takeoff.

When you realise that this fit-out is for the standard 44 seats, you realise how economy has been economised over the years.

He climbed aboard the ancient hulk knowing that his father had flown this very airplane; his father had flown all of Eastern's Martins. It had structural problems with a few of them losing their wings in flight.

This includes a flight crew operating manual, ground school, flight time that includes three takeoffs and landings, and placement on a seniority list that allows you to fly as copilot to future air shows. The next day the owner of N636X lowered the aft airstairs, and Whitesell discovered with delight that the interior was still in great shape.

Best of all is associating with people who share the same enthusiasm. Flying a Martin 404 also makes one appreciate the increased reliability and relative simplicity of turbofan-powered airplanes.

One other early conversion occurred in 1954 when D Napier and Sons in Britain converted 340s with that company's 2280kW (3060hp) Eland N.El.1 turboprops as the 540.

Convair's own conversion program involved Rolls Royce Darts, and the first of these flew on May 2 1965.

Two that spring to mind are the Allison 501 (military designation T-56) and the Rolls Royce Dart, with the former being the more common. He purchased and transformed a New Jersey farm into the popular Flying W Ranch, a unique fly-in resort with a Western motif.

WebThe Martin 404 was designed by Glenn Martin who established one of the first aircraft factories in 1909 (only six years after the Wright brothers first flight).

Beautiful shots taken while the sun is below the horizon, Accidents This was when airmanship, instinct, and timing seemed to play larger roles than they do today.

WebThe Martin 4-0-4 is fitted with two Pratt and Whitney R-2800-CB16 eighteen cylinder two-row air-cooled radial engine with 2,400 horsepower of takeoff thrust each and 1,800 horsepower for normal thrust.

But when two such aircraft appeared on the auction block in Billings, Montana, in 1994, they sold for more than he could afford.
