David Brown served in the US Navy during Vietnam.
"(I was deployed) in 1967 and 1968 for two, nine month tours."
Brown piloted an E-2 Aircraft, one similar to what Lt. Kale Nichols pilots currently in the US Navy. Its one of the many things that is similar with the two men.
"A lot of comradery ... all the aviators are very tight knit" Nichols said.
The main thing that brings the two men together, is actually a Navy Sword. The sword was owned by Brown for over forty years, and in 2008 he put it on EBAY to be sold.
"I decided to pass it on to someone more deserving" Brown said.
It would just so happen that the sword would be gifted to Nichols, going from one E-2 pilot to another.
"I never imagined it would come full circle" Brown said.
On Saturday, at the Niagara Falls Air Show, the sword and Brown were reunited after ten years after Nichols and a crew based in Virginia flew an E-2 aircraft in for the show. Brown and Nichols had never met before, but the sword brought them together.
