an atomic bomb was dropped over a city...

[optimistic pessimist]

Dear all,

1. In 1945 an atomic bomb was dropped on Hiroshima.
2. In 1945 an atomic bomb was dropped over Hiroshima.

When I first read an English texbook pubished in Japan, the preposition before Hiroshima was "on" as in #1. However, in a revised edition, the preposition is "over" as in #2.

Do you think "over" is better than "on" in the sentence above?

Thank you!

OP

"over' could have a couple of meanings here - the airplane carrying the bomb was over the city when the bomb was dropped and the bomb detonated over (above) the city, not on the city.
