The FBI and Homeland Security have issued a nationwide warning about al-Qaida threats to small airplanes, just days before the anniversary of the 2001 terrorist attacks.
Authorities say there is no specific or credible terrorist threat for the 10-year anniversary of the attacks on the World Trade Center and Pentagon. But they have stepped up security nationwide as a precaution.
The alert, issued ahead of the summer’s last busy travel weekend, said terrorists have considered renting private planes and loading them with explosives.
Aviation security is much tighter than it was a decade ago, but al-Qaida remains keenly interested in launching attacks on airplanes, believing large attacks with high body counts are more likely to grab headlines.
