Moscow airport bombing is a stark reminder of what aviation security is up against

As I continue to read reports coming in about the bombing at the Domodedovo airport in Moscow, I can't help but think that this should serve as a reminder to the public and aviation practitioners alike about what we're up against when it comes to securing the world's airports.

The latest news reports say 35 people have been killed and more than 100 injured from the blast that detonated in the international terminal at Moscow's busiest airport. Russian authorities are treating this as a terrorist attack, but no parties have yet taken responsibility for the attack.

Some are saying that this attack is evidence that Russia hasn't taken security seriously enough despite previous attacks:

Leonid Mlechin, an independent journalist who covers security issues, says the return of terrorism to Moscow shows that Russian security forces have failed to address the lessons of past terrorist attacks.

"This is a serious failure of special services," he says. "No one can carry out such acts alone. He needs to be trained, equipped, and supported by an organized group. Our intelligence services have clearly not been able to catch these groups."

While Russia has a long history of violence and unrest, those in aviation security in the U.S. and around the world must remain vigilant against such future attacks.
