This is the Boomber HB.1b, equipped with a bombsight.

How to use the bombsight:
1) Fly level at 6,000ft (2,000m), between 200 to 500mph
2) Wait for the sight to stabilize (hard maneuvres can cause it to wobble)
3) Drop bombs when the target approches the centre of the sight's camera

There's also a second bombsight for you to save as a subassembly. Delete it when you're done.

Remember, the bombsight isn't 100% accurate! There's a bit of leeway, so drop more than one bomb.

The Boomber HB Mk.1b is a mixed-power long-range heavy strategic bomber with a massive payload capacity. Normally it is internally loaded with 9 1000lb bombs, however there are multiple possible overload configurations up to 40,000lbs of payload. For self-defense it has an 'Angel Flares' system, which drops 25 flares in an angel-wing pattern when the V button is pressed. VTOL control also controls the flaps. At high speeds, it is reccomended to trim down the aircraft, as it will begin to pitch up because of its' high-lift wings.
