A pilot who was critically injured in front of thousands of spectators when his plane crashed at an airshow in Victoria says he has spinal damage but is on the mend.

Champion aerobatics pilot Glenn Collins was performing at the Avalon Australian International Airshow on March 28 when he was involved in an accident during a stunt.

Collins, aged in his 50s, was aboard a single-seat biplane and appeared to be performing a loop when he lost control and hit the runway.

He was airlifted to The Alfred in Melbourne in a critical condition with serious upper and lower body injuries.

Collins is a Sky Aces pilot for Paul Bennet Airshows, who on Monday posted an updated statement written by Collins regarding his condition.

Following a five-week stint in Melbourne, the pilot is now in a Sydney hospital, closer to family and friends.

“Most of my general injuries are healing well, but I do have spinal damage” Collins said.

“While I can move my legs – which I’m incredibly grateful for – I don’t yet have full feeling in my legs or waist. Ongoing rehabilitation will be key, and I’m giving it my all.”

Collins said his future was still uncertain but he remained “hopeful and grounded in gratitude”.

He thanked his family and friends for their support, as well as the medical staff in Sydney and Melbourne.

“I want to express my deepest gratitude for the incredible outpouring of support, kind messages, generous donations, and love I’ve received,” he said.

“It’s been truly humbling and has lifted me up during some of the toughest moments. Knowing so many people are in my corner means more than I can say.”

No one else was injured in the crash, which occurred away from crowds.

Collins is an expert pilot, having clocked 2700 hours in the sky, with over 1000 of those hours in ultralight and microlight planes.

His commercial experience also includes banner towing, skywriting and parachute displays, and additionally has 83 skydives to his name.

A GoFundMe has also been organised to help Collins financially.
