Engine Start??

[Al Capwn]

I've run into an issue where some of my key bindings stopped working and once I reset the controls to default and re-assigned what I wanted I haven't had any issues since.

If you setup custom key bindings you may want to save your current config from the in game menu to somewhere safe (or you can always just copy the files manually from your documents folder), and then reset the controls to default and see if you can get your plane started then.
