Incidents and accidents

Oops! It seems that a bug crept in with the flight update a couple of days ago which caused an error for users who hadn't entered any data yet. It should be fixed now - I've tested it out manually, and now I'm going to write a bunch of test code to catch problems like this before they make it to the main site. Also, every time there is an error on the main site from now on, I will get an email, so I'll be able to catch these things as soon as they appear. So, apologies for the problems, but we're good to go once again. Sorry about that!
