The Mystery in the Mon

At 4:10 PM on January 31st, 1956 a B-25 Mitchell bomber crashed into the Monongahela river (known to locals as "the Mon") just outside of Pittsburgh, Pennsylvania. The entire crew of six made it through the initial impact but only four survived the freezing Mon. For fourteen days the Coast Guard and the Army Corps of Engineers searched the river for the downed bomber. No trace of the flight was ever found. To this day the "Ghost Bomber" crash remains one of Pittsburgh's most legendary mysteries.
Conspiracy theories regarding the fate of the aircraft were quick to develop. Some think that the plane was carrying nuclear weapons or nerve gas. Others believe the flight was ferrying mafia money, a UFO, or even Howard Hughes. Residents of Pittsburgh still continue to speculate about the fate of the aircraft.
There were plenty of eyewitnesses to the crash and one might think that such a large aircraft would not be hard to recover. At the crash location the river was only 500-1000 feet wide and 25-35 feet deep. In comparison, a B-25 bomber is 52 feet long, 17 feet tall and has a wingspan of 67 feet. Its last location above water was well known and several people watched it for the full 15 minutes it took to sink.
Some believe that the Army secretly recovered the plane in the middle of the night in a secret operation, disassembled it, and had it shipped away. There are even eyewitnesses that claim to have watched the whole thing (one man later admitted making the story up as an excuse for his being out all night). They also claim they were threatened by men in uniform and told never to speak of the incident. How do these people account for the 14 day public search? They say it was nothing but a hoax meant to cover up the real rescue. Oh, some witnesses claim that they watched a mysterious 7th crew member being pulled from the river. It is true that the original flight manifest listed 7 crew members when it left its origin from from Las Vegas. One person was dropped off in Detroit. The destination of the flight was Olmsted Air Force base in Harrisburg, PA. The purpose of the flight was to pick up aircraft parts from Olmsted.
Like most conspiracy theories involving the government, their side of the story is somewhat less intriguing than that of the conspiracy theorists.
In short, something caused them to run out of fuel. Their course was altered and the engines shut off short of their new destination forcing them to ditch in the Monongahela river. You can read the rest of the official report here.
OK, So where is it?
Back in 1995, a local group of businessmen calling themselves The B-25 Recovery Group started a scientific investigation into the story of what really happened on January 31st, 1956 and the days that followed. They have mapped the bottom of the Mon with side- scanning sonar and gathered information on the ditching from governmental and civilian sources. The group has interviewed experts on subjects ranging from the design and construction of the B-25 to silt deposition in the Mon. Through careful investigation they have determined that the bomber accidentally slipped into an open gravel pit under the water and was quietly buried by the river.
Specifically, they believe it is buried approximately 150 feet off the left bank of the Mon, at mile point 4.9 at a place called Bird's Landing. Bird's Landing was once a tie-off point for barges. It was also known to be a favorite place for "gravel pirates" who dredged the river and sold what they had taken to customers all along the Three Rivers area. It was this dredging that opened the underwater pit that would eventually be the burial site of the B-25.
Why hasn't it been raised?
Money. Or lack thereof. It is $25,000 for starters to rent a metal detecting magnetometer and a crew to operate it. Once the location is confirmed, they would have to take samples of metal taken from the river bottom and analyze them to confirm that any metal found is identical to that used in the Mitchell bombers. Bob Shema, Operations Director for The B-25 Recovery Group states, "we expect to find the engine blocks, landing gear and tires-they were all made to be bulletproof...but the rest of the plane-doubtful".
Those of us familiar with the condition of the rivers around the Steel City in the 50's know that the water quality at that time was poor, at best. Life expectancy of any metal in the Mon's polluted water was 1/3 to 1/2 that of the neighboring Allegheny river. "You couldn't keep an outboard motor in the water all year - the propeller would be dissolved in no time. All the aluminum [of the plane] is expected to be gone, except what may have come in contact with the bottom," Shema said. Locals know that (ironically) you don't find steel in the Mon.
Why do people still believe the far out stories?
So, if we have a good idea of what happened to the flight and where it is, why do the conspiracy theories still abound? Well, for one thing, the plane ditched during the height of the cold war. Everyone was a little bit paranoid. The Pittsburgh area was surrounded by missile bases. The idea that our military was stealthy enough to sneak in at night and remove a bomber from the river undetected was somewhat oddly reassuring.
If you really sit down and start to think about the situation all kinds of questions should pop into your head. "Why would the government put nerve gas or nuclear weapons on an obsolete aircraft that was due to be retired in eighteen months?". There were plenty of aircraft more qualified for those kinds of missions by 1956. The B-25 that crashed was left over from WWII. It was a National Guard trainer being flown on the last day of month and the pilots were trying to get their monthly hours in. In the final analysis, they just ran out of gas.
