A North Texas-native was one of five people killed in a Tennessee helicopter crash on Monday.
Michael Mastalez, 21, of prosper was with his girlfriend on a sightseeing tour when it crashed near the Great Smokey Mountains National Park.
Mastalez’ friends and former co-workers from the golf course where he worked in Prosper said the young man was making plans to attend college in North Carolina.
"He was just an all-around sweet kid. Everyday working with him was a fun day, I mean he just always brought a positive energy,” said friend Whitney Williamson.
The NTSB will have a preliminary report on the crash by the end of the week.
