A man suspected of planning to blow up a Delta Air Lines flight in Detroit could face charges as soon as Saturday, according to an official familiar with the case.
There was nothing out of the ordinary until the flight was on final approach to Detroit, said Federal Aviation Administration spokeswoman Elizabeth Isham Cory.

That is when the pilot declared an emergency and landed without incident shortly thereafter, Cory said in an e-mail message. The plane landed at 11:51 a.m.

One U.S. intelligence official said the explosive device was a mix of powder and liquid. It failed when the passenger tried to detonate it.

The counterterror official said the passenger was being questioned this evening.

The passenger created a disturbance by lighting what was reported to be firecrackers -- or perhaps a "powdery substance" -- onboard the flight, injuring himself and several other passengers, according to Delta Airlines

FBI spokeswoman Sandra Berchtold confirmed today that agents are at Metro.

The man was apparently already on the government's no-fly list of suspected terrorists, ABC News said a senior intelligence official told them.

President Barack Obama was notified of the incident and discussed it with security officials, the White House said. It said he is monitoring the situation and receiving regular updates from his vacation spot in Hawaii.
