Fly under the R&D center bridge.

[Galane]

The bridge, it tantalizes the adventurous nature of the common Kerbal. They yearn to risk its tight clearances and sharp turn - in any sort of vehicle that doesn't depend on ground contact for support and steering.

10 points for flying under it with any sort of vehicle and not crashing into any of the R&D buildings.

+50 for a manned vehicle.

+75 for a rotary propeller vehicle.

+100 for a jet propelled vehicle.

+500 for a liquid fueled rocket propelled vehicle.

+700 for a solid rocket propelled vehicle.

+1000 for doing it without wings. (Not for slow hovers with a VTOL vehicle.) Wings may be installed for the approach then jettisoned, which could make the next score a bit difficult.

+500 for a safe landing anywhere after going under the bridge.

or

+550 for a safe landing back on the KSC runway or launchpad you started from.

No points off for taxiing from the launchpad or runway to a different takeoff position, but the takeoff must be outside the R&D center.

Highest speed under the bridge is trump for ties in points.

Note: Propulsion modifiers NOT cumulative. Use the number for the highest valued propulsion installed, which must be active during the flight under the bridge. The propulsion scored must be the primary motive power at the time of the passage, so simply sticking a couple of Seperatrons on a prop plane doesn't score 700 points.

Uhh, there's already a very similar challenge going on, here.
