It was recently reported that Air Force 2 aborted a trip to Guatemala on account of some strange noises heard on takeoff. So far Ms Harris has avoided any trips very far from D.C. presumably so as to be on the spot when Sock Puppet Joe finally can't be held upright through a short speech any more.
I'm speculating that the strange noises in V.P. Harris' plane can be traced to a rattling of loose marbles in Harris' head.
It also seems plausible to me that Nancy Pelosi has outfitter Harris' plans with a bomb to be used while she's speeding back to D.C. The fortunate twofer would make Nancy president.
