my son was comming down the ladder to look back up to see if roof flashing was straight,and I was looking up while holding ladder

At approximately 1:12 pm ,I was helping my son by steadying the ladder cause it was extended 25 feet up,he just finished installing one 12 foot piece of flashing and he climbed down the ladder halfway to get a better perspective view of installed work,looking up at a perfectly clear blue sky everywhere,and saw a hot white round object very high in the sky and fortunetely for me I was also looking up at the same time,the sun was to our west,so when a plane passes over it would be light up brightly,this was no jet aircraft,but a round brightly light up object from the bright sunlight, it was astounding to visually see this object ,it's speed was at least 1200 miles per hour,I was an exprienced air force crew chief at cannon air force base 88101,fixing brand new F-111A's for four years,also a Grumman employee building the F-14 super TOMCAT,this object was hauling butt going north east at an incredible speed, then slowed down to almost a stop and then went up straight up, the distance it traveled when we saw it to point of going up was at least 5 miles at that altitude.
