EACH year organisers of the David Hack Classic find something a little bit different to bring in the crowds and, for its 20th anniversary, it's an RAAF C130 Hercules.
The C130 - built by Lockheed Martin, is a tactical air-lifter measuring 34.4m in length, 10.1m in height with a wingspan of 40.4m, which can deliver cargo to short unsurfaced runways and airdrop cargo and paratroops by parachute and, depending on configuration, carry up to 128 passengers, 74 paratroops, 97 stretcher patients and two medical attendants or eight pallets of cargo.
This one is fitted out as a medivac plane and will be open for walk-throughs, organiser and Rotary Club of Toowoomba North president Robyn Jeffery said.
It is one of about 30 planes expected to attend the day, a number of which, including two World War Two fighters - a Mustang P-51D and Yak-3 Steadfast - will conduct paid joy flights courtesy of fighterpilot.com.au.
Over 300 classic, vintage and modern cars, convertibles, race cars, historic motorbikes, trucks and military vehicles are also expected.
"Every year we get some pretty spectacular cars from Model T Fords to Lamborghinis, Porsches, historic Holdens, Fords and Minis, to race cars and army vehicles," Robyn said.
"The enthusiasts really get behind it, and they are so passionate about their cars and aircraft, it's great to be able to go and talk to them about them."
The classic, which attracts up to 5000 people, is named in honour of David, whose passions were cars and photography, and whose life was cut short in 1998 by Non Hodgkins Lymphoma (Leukaemia).
The original event had been planned as a celebration for this 28th birthday at Toowoomba's Aerotec Hangar, but he didn't make it, and the Rotary Club decided to go on with the event as a fundraiser in his memory, with proceeds going to the Leukaemia Foundation, Blue Care and other charities.
David's mum Anna still presents the Public Choice Trophy, one of about 20 show categories, each year.
There is also a giant $5 raffle, with this year's first prize being a flight in the Boeing Stearman, donated by Aerotec and the Rotary club.
The David Hack Classic is on Sunday, May 20 at the Aerotec Hangar, Toowoomba Aerodrome, Spitfire Street, Wilsonton and is open to exhibitors from 8am and the public from 8.45am-2.30pm.
Tickets are adults $15, children under 12 free and a family of two adults and two teenagers: $40. Exhibiting costs $10 per vehicle.
