BOSTON — Model airplanes are suddenly on the public’s radar as potential terrorist weapons.

A 26-year-old man from a Boston suburb was arrested Wednesday and accused of plotting to attack the Pentagon and the U.S. Capitol with remote-controlled model planes packed with explosives.
    experts and model-aircraft hobbyists said it would be nearly impossible to inflict large-scale damage of the sort Ferdaus allegedly envisioned using model planes. The aircraft are too small, can’t carry enough explosives and are too tricky to fly, they said.
