Huge round silver disk hovering over neighbors house, writing on disk and roaring fire from disk

At about 2 AM, in Brooklyn about 1946 my sister came to my room and woke me.  She was very excited and said there was a big object across the street hovering over the neighbors house.  
It was about 40 feet to the neighbors house and the object was about 50 feet above the neighbors house and it was roaring like a jet with fire coming out the center of the disk.  There was writing like arabic or hieroglyphics around the sides of the silver metal disk.  
IT hovered about 5 minutes then with a roar ascended to about 100 feet and stopped,then gained speed on a horizontal plane and disappeared very fast.  
There were 3 withesses, myself, I now live in CAL and am 73, my sister who lives in NY and is 70, and my mothet who is 92 and lives in Cal.  We are willing to give you our account. 
We could never find anyone interested and do not know who to report it to.
Witness indicates that the date of the incident is approximate.  PD
