Earlier this year Jolie purchased the Cirrus SR22, one of the safest single-engine planes, with a base price of $334,700, that includes a parachute that will carry the entire plane to safety.
Jolie got her pilot's license last year, spurred on perhaps by Maddox. "Every time Mad sees a plane, he's amazed," Jolie, told PEOPLE at the time. "If I could actually fly a plane by the time he's 4, I'll be like Superman to him."
Lately, Jolie, Maddox and 9-month-old sister Zahara have settled in with Pitt in a home outside Calgary while the actor films The Assassination of Jesse James by the Coward Robert Ford.
In between daily set visits – where Maddox plays with the other children, including Mary Louise Parker's 21-month-old son William – Jolie and the kids like to shop.
On Oct. 8 they stopped by a charity exhibit selling paintings by Ghanian children. Jolie bought five pieces for about $850, including a whale drawing that Maddox chose.
She "looked like a great, grounded mom," says the event's organizer, Alisa Buckley. "She just has a glow."
