This isn't something that's going to be released anytime soon, if at all. Consider it a pet project like Maverick's intro. I'll post models of the items involved if people like. I have concept drawings for the interception craft which would be similar to an avenger (only more sleek and contemporary) and I'm in the process of drawing up the ufo which will be a similar design to a small scout.
Anyway on with the show.
Fade to scene from black. Starfield twinkling nebulae clouds in the background. Hold for 1 second to draw in the beauty of the scene and then a lower mid left of screen a small flash as reflection from the sun catches an object moving very quickly.
Object gets closer to screen very quickly leaving no doubt that object is a ufo. The ufo flashes past the camera shaking it as it goes.
Camera pans round to catch a glimpse of the ufo and begins to follow it. As the camera pans around a resplendent view of the earth comes into view complete with cloud cover and atmosphere.
The ufo zooms towards the earth and the camera follows it in. The ufo shudders, starts to glow and gives off sparks and flames as it enters the atmosphere and the camera starts to judder and shake as it follows in. This continues until flame and the red glow envelop the camera.
Cut scene to a mountain range. Camera pans up to see a large cloud rapidly forming (ala ID4) and the ufo breaks through it at high speed and flies overhead.
Cut to a blank screen where a red flashing light goes off and is accompanied by a klaxon.
Cut back to the mountain scene again where the inteceptor craft flashes overhead.
Cut to an overflight of water and the ufo being chased low over the water with full reflections by the interceptor craft. Camera moves from left to right over the scene. The interceptor craft fires as the ufo just flies over land. The missile hits the ufo and it goes down. Cut to camera following ufo down complete with camera shake. Ufo hits the ground and a cloud of dirt is kicked up. The ufo bounces after the first impact and goes down again. This happens twice more before the ufo stops moving.
Cut to the front of the ufo as it's crashing and coming towards the camera (ala men in black). It fianlly stops and kicks up a dust cloud which covers the view. Which is when the title logo comes out of the clouds and fade to black.
I've no idea if this is possible but I'm going to have a go at it
For now though I'm posting the concept of the crewed interception craft based roughly on the Avenger.
