This sounds pretty cool.

Google Inc. added more weapons to its query cache this week, rolling out tools that allow users to access travel updates and search by numbers for information on shipment tracking, patents and vehicle identification, for example.
Using the new search by number feature, Net users looking to track packages can now enter a United Parcel Service of America Inc. (UPS), FedEX Corp. or U.S. Postal Service tracking number into the Google query bar to locate their goods.
Users can also search by patents, Federal Airline Aviation (FAA) airline registration numbers, bar codes and telephone area codes, according to information posted to the company's Web site this week.
Google has also added new travel-related tools, allowing users to check the status of U.S. flights by typing a flight number into the query bar, or check the weather at a particular airport by entering the airport's three-letter code and the word "airport."
