WASHINGTON - (AP) - Transportation Security Administrator JohnPistole says the agency is asking government security experts ifthere is a way to make the security pat-down less invasive but justas thorough.

Pistole says there are no modifications planned as yet for theinvasive pat-downs that make some air travelers uncomfortable.

Undercover tests by government security experts factored intothe Obama administration's decision to use a more thorough pat-downso that screeners can catch a bomb hidden in a traveler'sunderwear.

A man charged in an attempt to bomb an airliner last ChristmasDay is alleged to have hidden a bomb in his underwear.
