So, you'll be cratering runways in the Blennie?
The magic words are "long delay fuse": there's some crazy stuff in some of the detonators, you can set 6 hours of more or delay, enabling you to technically get kills in the event of a lucky blast when you're not even logged into the server
For practical purposes of airfield denial during a couple of hours event though, you might want to go with something more practical like half an hour or so
