Is it a bird? Is it a plane? Nope, it's nun of the above!

SAN JOAQUIN COUNTY, California (CNN) -- Sister Clarice Lolich celebrated her 80th birthday with a leap of faith -- by jumping out of an aircraft and gliding back to solid ground by parachute. She jumped in tandem, with an instructor.

Sister Clarice, now retired, was an aerospace education specialist with NASA for 12 years. In that capacity, she traveled across the country teaching children about space and the NASA program.

Sister Clarice clearly likes adventures: apart from three skydives, she has also bungee-jumped, para-sailed and rafted through the Grand Canyon.
