Just what I need

I will be taking a couple of trips in the next few weeks. This is not helpful as I look toward them!

The latest airplane accident occurred earlier today when a twin-engine plane owned by Hendrick Motor Sports crashed in the Blue Ridge Mountains as it was approaching its destination, Martinsville, Virginia. All 10 aboard, mostly relatives of the owners of Hendrick's Sports, died.
Last Tuesday, a small plane en route to Kirksville, Missouri crashed, killing 13 of the 15 people aboard, as it approached the airport.
Two pilots died as their plane crashed approaching the Jefferson City, Missouri airport Friday, October 15.
The FBI are investigating small puncture holes discovered in two US Airways jets in Charlotte Monday October 18. Similar punctured holes were found on another aircraft in Orlando the prior week.
On two separate trips from Chicago, busses crashed in southern Missouri and southern Illinois. The one in Missouri resulted in 14 fatalities.
I am not a conspiracy buff, but all of these plane and bus crashes condensed in such a short period of time baffles me. Are they connected? Is there a common thread, such as local terrorism? Or are they all just isolated incidents?
