How many airplanes are there in the sky?

According to an estimate, approximately 102,000 flights traverse the globe on a daily basis.

This translates to roughly 8,500 flights taking off and landing each hour.

It is worth noting that a substantial portion of these 102,000 flights have longer duration, exceeding one hour.

Consequently, it is reasonable to deduce that at any given instant, there are easily about 10,000 airplanes cruising at various altitudes.

Now, the question arises: how many of these aircraft are scattered across the vast expanses of the ocean? Surprisingly, there is no comprehensive record of such occurrences.

However, delving into historical data, particularly during World War II, reveals a staggering statistic.

In that conflict alone, a total of 95,000 American aircraft were lost, and when you factor in the aircraft lost by Germany, Japan, the Soviet Union, and other nations, the number rises into the hundreds of thousands.

Admittedly, a significant portion of these aircraft met their demise over land, but given the enormity of the figures, it is plausible to speculate that perhaps 5% of all the aircraft lost during World War II — more than 10,000 in number — ultimately found their resting place on the ocean floor.

If this conjecture holds true, it becomes conceivable that at any given moment, there could be a greater number of planes lying at the depths of the world’s oceans than there are soaring through the skies.

This observation is intriguing because, initially, it may seem counterintuitive.

However, upon closer examination, it unveils a fascinating perspective on the distribution of aircraft across our planet’s vast expanse.
