Plot hole: Landy uses the code 4/15/71 to point Bourne to the training site address. But how does he know it is on the East side?

The Bourne Ultimatum (2007)
1 plot hole - chronological order
Directed by: Paul Greengrass
Starring: Matt Damon, Julia Stiles, David Strathairn, Scott Glenn, Joan Allen, Edgar Ramirez
Continuity mistake: When Bourne is talking to Firsch, the gun he is holding changes from a Glock in the shots facing Bourne, to a SigPro when the shots face Firsch.
Jason Bourne: Get some rest Pam, you look tired.
Noah Vosen: He's looking right at her.
Trivia: In the Tangier chase scene, Nicky and Desh are seen pushing past the citizens. These are not extras, Tangier was too crowded and the flow of the people was hard to control, hence the two actors are genuinely pushing through the crowd.
Question: Anyone know how he got into Noah's office towards the end? I saw him go up the stairs, but it appears he would need a key card to get in without breaking anything.





Answer: Knowing Bourne, he must have had a keycard on his person. Remember that Landy guided Bourne back to the CIA New York Headquarters; she could have easily slipped a keycard in the Taxi Cab when Bourne was being picked up at the airport. All he would have to do then is avoid being detected by using the fire exits (hence going through the back).
