Bombs away!...please.

I've flown into Berlin's Tegel Airport a few times and I can't say it ever occurred to me that old buried munitions would give the term "final descent" a new and slightly macabre twist. According to this piece in Der Spiegel (yes, I've been reading it a lot lately), the fact that there are WW II bombs buried under the tarmac is no secret. This coming spring, they'll finally be removed and disposed of from Tegel and another 500 give-or-take other sites (but who's counting?). Unexploded WW II-era bombs are actually not uncommon in Germany (here's an interesting article about that), along with other weaponry–a construction site in Berlin recently uncovered a stash of weapons. That I knew. But the fact that there are live bombs close to the surface of an active runway at an international airport–bombs which become more unstable as they age–and it was known does make me wonder. Did the authorities calculate the odds? Every 9 out of 10 planes? Anyway, who am I kidding? I wouldn't have changed my travel plans even if I had known. I like a gamble.
