Dr. Felix Oragwu is a nuclear physicist and the arrowhead of the scientific and technological innovations that sustained secessionist Biafra during the thirty months of the Nigerian civil war.Ogbunigwe, the deadly mass destruction missile that made the federal troop jittery, was a product of the scientific feat of Biafra.

Between late July and early September 1967, it was reported that Biafra enjoyed air superiority over Nigeria by mere possession of an old 1939-1945 war vintage B.26 Bomber. One early September morning in 1967, the old B.26 was, as usual, primed for action at the Enugu airport, where the bomber was normally stationed preparatory for its routine bombing trips on military targets in Nigeria.
A Bofor ground to anti-aircraft gun located near the Enugu Airport defended the airport and the bomber. The primed B.26 bomber was ready to take off, at about 0630 hours on that fateful day to Nigeria, when suddenly there appeared a fast moving, low flying Russian MIG 15 Jet fighter, over the Enugu Airport and Biafra airspace for the first time since the war began. No member of the Science and Technology (S&T) Group before this incident had witnessed a MIG Jet fighter in action. The MIG jet fighter promptly attacked the airport and deflated the tyres of B.26 bomber, thereby immobilizing the vital warhorse.
“Later in the evening of that eventful day, the Commander of Biafra Air Force, after recovering from the shock and humiliation of the morning incident, summoned his officers, including the commander of Biafra Army engineers and some leading members of the S&T Group to the Enugu Airport for advice on the matter and what to do to bring down the low flying MIG jet fighter without the ground-to-air anti-craft guns.

“The Air Force commander, in shaking voice, informed the small group assembled of the MIG 15 Jet incidence of that morning and the implications for Biafra short-lived air superiority over Nigeria.”
With the emergence of MIG jet fighters in the federal troops’ arsenal, the use of B26 bomber had come to an end. The ‘Bofor’ gun at the Enugu Airport had become irrelevant against fast moving low flying jet fighters

Therefore, the Air force commander sought for what could be done to contain the jet fighters and maintain the morale of the Biafran troops and the population at large.
“In the course of the deliberations, a number of suggestions were made. The most viable was to find a mechanism for sending up debris, dust, small pebbles and the like in the path of the flying jet fighters in the hope that these dust particles could be sucked in by the jet fighters to impede its propulsion, asphyxiate and bring the jet fighters down. The question was what type of mechanism could be produced easily and quickly in Biafra to accomplish the task.

“To utilize this scientific principle in throwing up the debris in the path of a fast flying Jet fighter, the S&T-Group had to solve two problems. The first was the rotation of the debris in the bucket to set up laminar flow without allowing the latter to spin, the second was to generate such a recoil that the reaction to the recoil could impart sufficient energy to the rotated debris to rise far beyond the rooftops and spread the contents over a large air space.

An engineer member of the S&T Group called William Achukwu, Agricultural Engineer, volunteered to design and fabricate a metallic bucket-like system for the trials.

“A series of trial tests with varying masses (light materials) and sizes of the debris respectively, depending on the mass/sizes of the debris, gave excellent results achieving heights of 30-1000 feet (10-300 meters) respectively depending on the mass/sizes of the debris. The Air Force commander, the military personnel present, and members of the S&T Group present who witnessed the feat achieved, were very excited and went into jubilation. Most people were convinced that the new mechanism was an answer to the jet fighters, and the S&T Group was directed to produce many of the devices to be used not only at the airports but also as air defense cover at various Biafran troop locations.

“In October 1967, the federal troops, having captured and secured Enugu, the capital of Biafra were on their way to Awka and Onitsha, the commercial nerve centre of Biafra, through the old Enugu-Awka-Onitsha road. The well armed, heavily equipped federal troops, with their superior fire power, encountered a battalion of poorly equipped, out-gunned and virtually exhausted Biafran troops at the Ugwuoba Bridge, few kilometers into Awka. However the Biafran troops had on hand some of their air defence dust mines. Unable to withstand the superior firepower of the federal troops, they began to run for their dear lives carrying along with them their air defence ‘mines’. Their resourceful commander.
ordered them back and commanded them to place the air defence mines horizontally rather than vertically as designed and fire them on the approaching federal troops to see what would happen and thereafter run for their dear lives. The command was promptly carried out. Indeed, the federal troops could not understand what hit them. The effect of the horizontal detonation of the air defense dust mines was very devastating leading to loss of many federal troops, as well loss of large quantities of arms and ammunitions some of which got completely burnt. The devastation was, indeed, very extensive particularly in the unintended loss of military personnel, some of who died from the shock waves generated by the unexpected explosions. The mass of water, from the river below the bridge, was thrown up and widely spread by the generated waves, thus adding to the trauma of the advancing troops.

“The following morning some members of the S&T Group were summoned to Ugwuoba Bridge by the military to help explain the new phenomenon and what really had happened to make the air defense dust mines accomplish what they did. Meanwhile, the people of Amansi Awka, the neighbouring village, were called out to the scene to help in burying the dead. An elderly man from Amansi Awka on seeing the large number of dead soldiers along the bridge exclaimed in Igbo: “ogbuefa n’igwe” (the dust mine had killed them in masses or massively). That was how the otherwise anti-aircraft “Air Dust Mine” got its name ogbunigwe (mass killer) and the S&T Group came to be referred to by the generality of the Biafra public as ogbunigwe people.

“Arising from the Ugwuoba incident, a device designed and fabricated as an anti aircraft dust mine had suddenly become useful as a ground-to-ground weapon with devastating impact beyond imagination. Its new mode of deployment provided Biafra with additional ammunitions. This incident vindicated the adage “that necessity is the mother of invention.”

Ibo and their fake war stories



There is GOD






Anyway am coming let me ask my gfrnd weda nah true the op dey talk 1st

softmind24:
Ok

heheheheh,hater.

Half of a yellow sun

The o.p and his ilk are lettered illiterates. Did you attend a decent college at all.are you saying that ibos achieved nuclear fusion, you slowpoke. My illiterate ibo beer joint owner told me the same fable and said that ojukwu surrendered after using the weapon because it killed too many hausas and ojukwu felt pity for them.

a sand catapult? what an 'invention'.so lame!

I see "mass destruction" and "Nuclear physicist" and I thought the article might be worth the read but seriously?

This is nothing more than a shrapnel grenade. Can even be made at home with gun powder, a fuse, sharpnel (bottles, nails, sharp finely cut stones) and a container. That cannot even work against aircrafts which it was designed against.

IGBOS are really Great!

How many have d yorrobas invented,how many wars have they fought and survived,in 1993 Abiola declared him president elect and d yorrobas fight didn't last more than 3days because of ur cowards

Do u even knw how to make a common catapult?

I don't care about the tribe or ethnic or BS like that. I am bothered about a shitty article

The "yorrobas" had invented wrestling matches over cocoa yam tubers known as Kiriji wars.

what is shitty about this article? Is it that there was no such thing or what?

And who told you it didn't work against the MIG jet it was designed against. Or is it because the OP was interested in the event leading to the weapon been called 'mass killer' (ogbunigwe). The destroy of the B26 bomber of the Biafran Army was little of what necessitated the design of the ogbunigwe. It was the series of attack and killings caused by the MIG jet on Biafra that the thought of designing an anti-aircraft jet bomber came to mind. The said weapon was detonated vertically and horizontally. Vertically when it was used to destroy the MIG Jet fighter, and horizontally at Umuogba bridge where it got its name. These events gave not only the Nigerian Army a big shock, but even the Western world.
