Rex Denning

Rex Denning was a Human male who lived during the 19th and 20th centuries. He had served in World War II and, by 1947, was a lieutenant general in the United States Army Air Corps

Following the crash-landing of an extraterrestrial spacecraft in Roswell, New Mexico in July 1947, President Harry S. Truman ordered General Denning to find out all that he could from its Ferengi occupants Quark, Rom and Nog. He remained unaware that the three aliens had been accidentally sent back in time from 2372. He was deeply suspicious of the Ferengi, whom he consistently referred to as "Martians," and believed that they were planning to invade Earth. His subordinate Captain James Wainwright agreed with this assessment of the ersatz Martians. The Ferengi were kept in Wright Field while their vessel was stored in Hangar 18 of the facility.

Seeking to create a new and better alternate timeline in which the Ferengi would be much more powerful and influential than in the original one, Quark attempted to open up trade for advanced technology with the United States government by negotiating with Denning. However, these attempts caused Denning to distrust Quark even more as his behaviour reminded him of his brother-in-law, a used car salesman. He was also concerned that Quark would make good on his idle threat to supply technology to the Soviet Union.

After reporting back to President Truman, General Denning had the Ferengi detained for interrogation and ordered Wainwright to discover their true purpose in visiting Earth. However, Quark, Rom and Nog were able to escape with the assistance of Professor Jeffrey Carlson and his fiancé Nurse Faith Garland. While Denning and several MPs nearly apprehended the Ferengi, they were incapacitated by Constable Odo, who had stowed away on Quark's ship. The four time travellers returned to their own time by recreating the time warp. Denning then told Captain Wainwright that the cover story was that they had found nothing more than a crashed weather balloon. 

The unofficial Human-Ferengi first contact became known as the Roswell Incident. Despite the US government's continued assertions to the contrary, rumours that an alien spacecraft crashed in Roswell persisted into the 21st century. (SS TOS (Whales Weep Not), )
