Interesting. Could Stern have flused it same as Daniel? Possible. Interesting Star Magazine is standing behind their story that it looked like a pharmacy in the room... of course, they did have to get through customs.
Unless you're Rush Limbaugh, US Customs in FL, do not thoroughly check private planes, and I don't know if they arrived in private or a commercial plane.
Futhermore, prescription drugs are permitted and we have been told that the drugs were in the name of HKS.
