In very rough figures the B-29s were flying at about 30000 feet of altitude when they dropped the bombs and the bombs exploded at about 1500 feet of altitude. You can estimate from there.
UNITED STATES STRATEGIC BOMBING SURVEYSUMMARY REPORT(Pacific War)WASHINGTON, D.C.1 JULY 1946The amount of bombs dropped were measure in tonnage not according to the times they dropped bombs or how many bombs were dropped. Pegalita of Answers ComThe total tonnage of bombs dropped by Allied planes in the Pacific war was 656,400. Of this, 160,800 tons, or 24 percent, were dropped on the home islands of Japan. Navy aircraft accounted for 6,800 tons, Army aircraft other than B-29s for 7,000 tons, and the B-29s for 147,000 tons. By contrast, the total bomb tonnage in the European theater was 2,700,000 tons of which 1,360,000 tons were dropped within Germany's own borders.
While I do not have an exact answer for you, I can tell you that the Enola Gay was selected by Tibbets on May 9, 1945 while it was still in the assembly line and it was accepted by the Air Force on May 18, 1945. It was part of the second batch of Silverplate B-29s, modified by Tibbets to carry the atomic bomb. A total of 15 Silverplate B-29s were manufactured.
The basic reason the US needed to capture any Pacific island was to put airfields on it from which land-based aircraft could operate and dominate the surrounding area, and to deny the use of the island to the enemy for that same purpose. The Navy had aircraft carriers, but these were very expensive, took several years to build, and could be swiftly sunk by a submarine firing torpedoes, or lost in battle. At the time Pacific islands were sometimes referred to as "unsinkable aircraft carriers". As soon as enough of the island was secured to begin, construction was started on an airfield, and as soon as that was far enough along combat planes began operating from it, to relieve the necessity of the Navy risking its precious carriers in the area of the battle to provide air support. The first island campaign was on Guadalcanal, in the Solomon Islands. This operation had to be launched in a hurry because the Japanese were building an airfield on it, from which, when it was completed, they could interrupt the flow of supply ships from the US to Australia. In the case of Iwo Jima, the Japanese had airfields on Iwo, and the US had massive bomber airfields they had built in the Mariana Islands, from which B-29s flew to bomb the Home Islands of Japan. These B-29s passed close enough to Iwo coming and going that Japanese fighter planes from Iwo could harass the bombers, and also the radio based on Iwo could send an early warning to Japan of an impending raid. Once captured Iwo served as an emergency landing field for B-29s shot up over Japan or experiencing mechanical trouble, aircraft which would have otherwise been forced to ditch in the vast, trackless expanse of the Pacific. Around 700 planes made use of Iwo for emergency landings. Iwo also provided a base for US fighter planes, whch had a shorter operational range than the bombers. From Iwo they could escort the B-29s to Japan and protect them from Japanese fighter attacks. Okinawa was valuable for among other reasons it was a large island, capable of holding many airfields, and was well within range of Japan's Home Islands for land-based aircraft, which could be used to support the eventual invasion of Japan.
B-29s are military airplanes designed and produced by the United States that were utilized in World War II and also in the Korean War. These bomber-aircraft had four propeller-driven engines and went by the nickname of "Superfortress".

There are 5 20s in a 100.

Two B 29s called Enola gay and Bockcar.

America's Boeing Company produced the B-29.
In very rough figures the B-29s were flying at about 30000 feet of altitude when they dropped the bombs and the bombs exploded at about 1500 feet of altitude. You can estimate from there.
Enola Gay and Bockscar both dropped Atom Bombs on Japan in WWII.
Boeing built 3970 B-29s, but not all saw service in the war. The B-29s operated almost exclusively in the Pacific and China against Japan. There were no B-29 raids in Europe. Almost all B-29s were assigned to the US 20th Air Force. At first an effort was made to base the B-29s in China, supported by forward bases in India. This did not work out. Supplies of every type had to be flown in to the forward operating bases in China from India, over the highest mountains in the world, the Himalayas. Cargo pilots called this "flying the hump". This supply bottleneck kept any great strength from being built up to operate from China, and aircraft levels never reached half the initial goal. After the Mariana Islands were captured in the summer of 1944 the B-29 units of the 20th AF were based there, and eventually all B-29 units were withdrawn from China. Five huge airfields were built in the Marianas, each home to a Bomb Wing. A Wing had four Bomb Groups. A Bomb Group had three Squadrons, each with about 16-18 aircraft assigned. The goal for each Squadron was to try to get 12 of these into the air for any mission. So each wing had between 192-220 B-29s on its airfield, and there were a total of 960-1100 in the Marianas if every squadron was at full strength.
