Certainly not the ugliest.... but I always thought the B1900 was ugly looking.... Great Plane though!

In the words of Eric Cartman, on the Ginger Kids Episode, EW! SICK!

Westland Lysander ,RAF

Yes this would have to be the ugliest!

Mad Max - Piloted by Bruce Spence; film credits call it "The Flying Jalopy".

True, but that variation is a glider. The landing gear of the 163 was designed to fall off after takeoff, so while it was afloat, it didn't look that bad. But when it was parked on the ground, whoah-nelly was it hideous.

Oh and a nice paint job will make any model look half decent, just watch What Not to Wear on TLC..

Hmmm This one needs to be aware of AD; 14 CFR Part 39
[Docket No. FAA-2009-0622; Directorate Identifier 2009-CE-034-AD;
Amendment 39-15999; AD 2009-18-03], RIN 2120-AA64

Airworthiness Directives; Pilatus Aircraft Ltd. Models PC-6, PC- 6-H1, PC-6-H2, PC-6/350, PC-6/350-H1, PC-6/350-H2, PC-6/A, PC-6/A-H1, PC-6/A-H2, PC-6/B-H2, PC-6/B1-H2, PC-6/B2-H2, PC-6/B2-H4, PC-6/C-H2, and PC-6/C1-H2 Airplanes

Findings of corrosion, wear and cracks in the upper wing strut fittings on some PC-6 aircraft have been reported in the past. It is possible that the spherical bearing of the wing strut fittings installed in the underwing can be loose in the fitting or cannot rotate because of corrosion. In this condition, the joint cannot function as designed and fatigue cracks may then develop. Undetected cracks, wear and/or corrosion in this area could cause failure of the upper attachment fitting, leading to failure of the wing structure and subsequent loss of control of the aircraft.
We are issuing this AD to require actions to correct the unsafe condition on these products.

Think the Demon Deacons could use a vertical wind tunnel!

That would be true if this were a Pilatus aircraft. However it's not.
Ever heard of a UV-18?

Shorts had a history of building some ugly airplanes. For instance the SB.3 which looks as if it has a problem with its proboscis.

Or the SC.1 for example.

And Boeing engineers must have had a bad night before they came up with the X-32B. That Joker-like intake and overall shape, if it had won, would have had fighter pilots wearing C-5 patches when they entered the bars.
