Didn't have a parking brake either - seat strap tightened around the emergency pneumatic brake handle worked OK provided pneumatics didn't deplete before you got the chocks in.
Great multi-role aircraft from the days when the weapons went where the crew aimed them - no kit errors, just poor weaponry if you missed.
And the Suu-23 was something else - what a wonderful noise and a real tight bullet group.
Rockets too - much better than those cluster things that so upset the civvies but did square root of bu**er all to the target.
Still enjoy seeing it as a gate guard - the last fighter in the RAF with real character.
