When you enter an airport and the distance, the distance calculator gives a list of airports withing that range. If you click the distance at the top of the list, it arranges the airports by distance. However, the results are not correct. For example, there are 3 airports with the distance. A-50, B-100, and C-555. If you try to sort by distance, it should give you ABC, but it gives you BAC. It sorts the first digit of each distance not by the actual numeric value.
