I'm not doing anything of the sort. I know bombs are still there from WW2. Just because there are still bombs from WW2 does not mean that every bomb that goes off is from WW2. While it is likely that the bomb is from the war, I haven't seen what evidence they have confirming that. That is all I am asking for.
The evidence is likely simple deduction, as in asking "when was the last time this area was bombed" combined with the history of the airport (built for the military in 1943, later converted to civilian use) and also noting other unexploded bombs have been unearthed in the area.
For it NOT to be a WW2 bomb would mean somebody sneaking in another bomb and paving it under the runway without being noticed.
There is a perfectly plausible alternative. A bomb fell off a plane after the war. This happens from time to time and has even happened with a nuclear bomb!
Yes, and it results in a huge amount of paperwork. You can't just randomly show up at your destination missing a bomb - especially during peacetime. They'll be combing over every part of your flight path to find it.
It could've also been intentionally buried there by bored soldiers, or placed there by airport maintenance people as a prank, or ended up there due to a freak teleporter accident. Maybe it was even put there by Godzilla. Maybe the Infinite Improbability Drive spontaneously materialized it, together with a bowl of petunias.
If you find a bomb in an area which is known to have been bombed, without any evidence to the contrary it is pretty safe to assume it's there due to the bombing.
Sorry about that. The article obviously doesn't explain. Here's my thoughts on it.
I don't think they did any exhaustive research. They didn't have to.
You would be able to look at the crater and see sizable pieces of a military air-dropped bomb. Normal bombs don't disintegrate. If they send it to a lab they can tell what explosive was used in it, which will roughly tell you when it was manufactured. (Assuming they don't find a serial number.)
That by itself is hardly conclusive, but that completely changes when you find identical unexploded bombs buried in the same area.
It would be rather odd if somebody came along later and put the same kind of bomb used in WWII in the ground. When the bomb got there isn't that important.
We are still finding unexploded artillery shells from the first world war in France. Germans are still finding bombs in cities.
The chemicals in the fuses mix and become unstable over time. The explosives don’t degrade as much.
If you wanted further verification, the bomb casing leaves fragments and explosives leave residue.
