A delay to 2nd quarter seems bad, given how low the flight rate is already vs number of passengers waiting. Is that delay a FAA requirement?
The alignment pin can be clearly seen falling away from the WhiteKnightTwo pylon with the release of SpaceShipTwo Unity in the @virgingalactic publicly released flight video
The pins looks like it came close to hitting the vehicle.
It is one of two heavy metal pins that align SS2 with the WK2 pylon as itís raised into place for mating. Once in position the pylon hooks are closed & they take the flight loads. It could be a bad day if the pin impacted the pressurized hull.
