Bugs

 * Sometimes, after boarding the vertbird, it will fly off straight to the south-east without stop, bringing you off map. (proof)
 * Using a weapon with the legendary 'Kneecapper' effect against the attacking Vertibird will instantly destroy both of the flyer's turbines but at the same time make it impossible to destroy completely. The Vertibird will then tumble around erratically for some moments before resuming its attack indefinitely, thus preventing the mission from progressing to the next stage. Use any other available weapon to avoid this bug.
 * When dropping off the player towards the end of the quest after the Prydwen explodes, Tinker Tom may be shot down by remaining Brotherhood Scribes. This will cause The Nuclear Option (Railroad) to fail and Desdemona will only repeat the line "Don't wait too long. The Brotherhood could be back in here any minute", making the quest impossible to complete. This can be fixed by reloading an older save.
 * A glitch may occur if Deacon is wearing power amour where he won't board the vertibird. To fix this load a previous save where you are not on the vertibird and travel away from the location. When you travel back he should be on the vertibird.
