The RC jets Ferdaus was intending to use were 1/10 scale. I fly both RC airplanes and helicopters. Below is a recent video of me flying my electric powered 1/4 scale Extra 330SC, which has a wingspan of 72”, a length of 72” and weighs in at 10.14 lbs.

The 330SC could easily transport 2 lbs. of explosives. Sure, 2 lbs. of C4 won’t bring down the Pentagon, but it could still kill many people upon detonation. Also, one coule easily fly an RC airplane loaded with explosives into a crowd of people. The threat of using RC aircraft as a terrorist weapon is very real. However, my fear is that this incident will cause a knee-jerk reaction by the Obama Administration and/or Congress to heavily regulate the use of RC aircraft. Just as with guns, there are responsible owners and there are criminals.
Nice plane!
