Aurora, Nebraska. The US National Weather Service received reports of large hail in Aurora, Nebraska, during a hailstorm on Sunday, June 22nd, 2003. It has been reported that the hail had penetrated the roof of a home, leaving holes in the structure large enough to crawl through. The stones were saved and placed in a freezer at the residence until the NWS assessed and confirmed damage and size of the hailstone.

The hailstone measured 6.5 in (16.5 cm) in diameter with a circumference of 17.3 in (44 cm), weighing roughly 1.33 lb (0.6 kg). This compares to the Potter, Nebraska hailstone on July 12, 1928. The Potter, Nebraska hailstone was 5.4 in (13.7 cm) in diameter and weighed approximately 1.5 lb (0.68 kg). So far the largest hailstone on record occurred in Coffeyville, Kansas on September 3, 1970. This stone measured 5.7 in (14.5 cm) and weighed 1.67 lb (0.76 kg)

The biggest recorded hailstones in the UK had the sizes of tennis balls 2.75 in (7 cm), weighed 142 grams and fell on Horsham, West Sussex, on 5 September 1958. However, hailstones weighing 1 lb (0.45 kg) were reported to have fallen at Plumstead, London, in July 1925. Mere tiddlers compared to the ballistics that rained down in the Gopalanj district of Bangladesh, 14 April 1986. These one-kilogram (2.2 lb) hailstones killed 92 people.

On May 27, 2003 a hailstone left a hole the size of a football in an BMI airbus which had more than 200 passengers on board. The BMI plane was flying to Manchester Airport from Larnaca, Cyprus when it encountered heavy turbulence within a thunderstorm over Germany. The plane landed safely inspite of the considerable damage. On April 14, 1999 hailstones the size of tennis balls fell on the eastern suburbs of Sydney, Australia, causing damage costing an estimated 150m Australian dollars and ruining 100,000 cars.
