Regular Contrails

about this morning's patterns in the sky of the symbol for remembering the hostages... there was a lot of chatter about who was behind it..
initial reports said that it was NOT done by the Air Force or an Air Force pilot but was a private civilian initiative.
Nice.
Later in the morning conflicting reports came out saying it was Air Force pilots that did it (not clear if it is was one pilot of multiple pilots in different parts of the country.
Ok. Nice.
Then later in the morning another report came out saying that the Air Force looked into it and it was an Air Force pilot but it was not intentional and just happened as part of regular flight patterns.
Funny.
Pilots normally fly around the country doing loops back and forth as part of their normal routines? Why aren't we seeing these contrails in these shapes on a regular basis? Or maybe they do different designs at different times as part of their normal routes, but we dont normally see these contrails at all, let alone in any variety of designs.... 
This was just a silly statement by the Air Force.
