"The President's travels and the TFR's, Temporary Flight Restrictions, which result are published and disseminated constantly by the FAA.
To be ignorant of them means the pilot never checked nor did he receive an official weather briefing via a Flight Service Station which would have contained them."

Are pilots required to check such things before they take off?
I'm not being argumentitive, I honestly don't know.
The plane I saw on TV was just a piddly little thing, the kind I assumed could just take off or land on any grass strip as long as the pilot had a license. No need to check with anybody as long as the pilot stayed in the mapped space where such joyrides are allowed.
