Very Strange

Today, a Thunderbird pilot and airplane crashed in Colorado at about the same time a Blue Angel presumably was killed in Tennessee when his plane crashed during a practice run. The Thunderbirds were doing a flyover for the graduation at the Academy and President Obama was in attendancen
The Thunderbirds are out of Nellis AFB while the Blue Angels are out of of Pensacola Florida.
These are the best pilots and crew of the Air Force and Navy and at almost the same you have 2 planes go down?
Something doesn't seem right to me.
I hope they check for terrorism and sabotage.
Update: apparently, both planes that crashed were both number 6. Strange.
