Description

The National Air and Space Museum of the Smithsonian Institution is one of the world's most visited museums. Almost all space and aircraft on display are originals or the original backup craft. Stand out items include, inter alia: Charles Lindbergh's Spirit of St. Louis, the Bell X-1 (broke the sound barrier), the Apollo 11 Command Module Columbia and the Friendship 7 capsule which was flown by John Glenn (first American orbital spaceflight).

Access & Transport

The museum is on the southern side of the National Mall, just west of the US Capitol and Botanic Garden. The closest public transport options are 'L'Enfant' train station (Fredericksburg and Manassas lines), 'Federal Center SW' (Blue, Orange, Silver lines) and bus services along Independence Ave SW and 7th St SW. Parking is $18.

Instructions & Recommendations

Note #1: free timed-entry passes are required and can be booked online ahead of time. Note #2: the Washington DC complex is going through a multi-year upgrade and is has already partially reopened with upgrade works continuing until 2026. The Museum’s second facility, the Steven F. Udvar-Hazy Center is located just south of Dulles Airport’s runways in Fairfax County, Virginia. It is open daily from 10:00 am – 5:30 pm. Visit the website: https://airandspace.si.edu/udvar-hazy-center

Meta review

The museum is considered as one of the must-see in Washington DC by travel guides and blogs. Based on past reviews, most visitors did enjoy it, both visually with originals or replica well in sight and plenty of informational content. However, the ongoing construction work does impact the quality and depth of the experience and the place can be very crowded in the summer months.

Environmental & Social

As part of the building upgrade, there will be significant sustainability improvements: rain harvesting, LED lighting, improved chilled water and steam systems, etc. The building will be LEED Gold standards. Educational and conservation aspects + also houses a research team.

Conclusion

Highly recommended for families and any space or aviation enthusiast. This is easily one of our favourite museums in DC.

For queries relating to cookies policy, please contact us through this form and select the following topic: “Terms, Privacy and Cookies”.

Privacy Policy

A) Definitions and why we have a privacy policy

A privacy policy is a statement or a legal document that disclose the ways a company collects, uses, processes, handles and discloses a customer or client’s data.

The need to have a privacy policy originates from regulatory requirements (applicable according to the location of data handling and processing but also your location) as well as from the use of third-party services that expressly require us to have one. The last reason is simply that we wish to be transparent with you, no questionable practice here.

Our policy is based on the EU General Data Protection Regulation (GDPR), a regulation set forth for people located in the EU. It is widely considered to offer the most comprehensive user right protection framework, which is why we are applying those principles to all our users and supplementing them with additional local requirements if needed.

The following privacy policy covers the Services provided by Koralgo, as defined in our Terms of Service.

When this policy mentions “Koralgo”, “we”, “our”, “us”, it refers to the Koralgo company responsible for your information under this policy. The definition of all defined terms can be found in our Terms of Service agreement.

B) Collection of information

Koralgo collects information in two different ways.

(i) Information you provide to us about you and others

Koralgo requests the following type of personal information when using the Platform so that it can provide the Services:

• Account information when you sign up such as your name, contact details, gender or date of birth
• Personal information relating to other guests or customers when completing a purchase or booking such as name, delivery address or date of birth
• Identity verification information such as Passport or ID details
• Payment information such as credit card details to be able to process payments and complete bookings or purchase
• Content of communications with us and between Customers and Sellers
• For Sellers, details relating to the assets, products and offers marketed on the Platform, including data such as price and inventory

The legal basis for doing so is that the collection and processing of the above type of data is necessary to enable Koralgo to provide the Services, including the administration of bookings and processing of payments.

(ii) Information we collect automatically

When you navigate on and use the Platform, we collect various types of additional information:

• Geo-location information through data provided by your mobile device GPS or IP address which enables us, for instance, to show your location and that of properties on a map
• Log data and usage information such as the pages you visited or bookings you have made, access time and duration, crash data as well as cookie data
• Payment transaction information such as amount, date and time, payment method and instrument for record keeping, fraud prevention and, generally, provide you with the Payment Services
• Device Information such as hardware and software information
• Cookies and similar technologies as per our Cookies Policy

The legal basis for doing so is to optimize the quality, reliability and overall user experience of the Platform as well as ensure the provision of the Services.

C) Usage, processing and sharing of information

Generally speaking, we use, process and share your personal information for security and authentication purposes, to enable us to provide the Services and improve their relevance to you as well as to communicate with you or comply with our regulatory requirements.
(i) Provide and improve our Services
We use and process the information so you can browse and navigate on our platform in a personalized and efficient matter and we can provide the Services. This includes sharing of information with Sellers to complete bookings or purchases.
(ii) Security and authentication
We need to be able to identify and authenticate you in certain situations such as when you log-in on the Platform or detect and prevent fraud – for this, we need to access and use your personal information.
(iii) Access and use the Payment Services [including data sharing]
We also share your personal information with our Payment Processor at the time a transaction is being processed. It is a leading player in that space who also has its own comprehensive privacy policy.
(iv) Improve our profiling
One of the strengths of Koralgo is the ability to provide you with what our algorithm computes as the best offers based on your preferences and search parameters. To achieve this, using and processing personal information is key to improve our profiling, whether it is based on what you tell us or through other methods such as A/B testing or calibration through meta-data. In the latter case we use anonymized meta-data.
(v) Provide analytics services to Sellers
Using anonymized personal data and meta-data relating to profiles, we can also provide ground-breaking analytic services to Sellers, so their offers and pricing strategy is optimized taking into account the potential customer base and competitive landscape.
(vi) Provide marketing services to Consumers and Sellers
Sharing anonymized personal data and meta-data with Sellers also enables us to provide marketing services to both Customers and Sellers that are more relevant and targeted, respectively.
(vii) Communicate with you
Being able to respond to your query, send you a booking or purchase confirmation or a reminder also requires us to use your personal information.
(viii) Sharing with Services Providers and Corporate Affiliates
We use Service Providers globally who may need to access personal information. They are contractually bound to protect such information and restrict their use to the task they need to perform. We may also share personal information to provide the Services within the Koralgo group of companies.
(ix) Regulatory requirements and business transfers
Compliance with regulatory requirements in various jurisdictions may also require us to share personal information. Finally, if Koralgo is involved in a merger, sale, reorganization or bankruptcy / insolvency, we may sell or share some assets as part of that transaction. If your personal information is part of those assets, we will notify you before the event takes place and your personal information becomes subject to a different privacy policy.

D) Transfers, storage, and protection of information

We operate and share information globally, both internally and externally (suppliers, consultants or service providers) in accordance with this Policy. Your information may therefore be transferred internationally, stored and processed in different countries in order for us to be able to provide you with the Services and access to the Payment Services.

Koralgo and the Platform developers have designed comprehensive security features and process to ensure the safety and integrity of the data stored by the Platform. We will retain your personal data as long as is required for you to use the Platform, enable us to provide the Services and in accordance with legal and regulatory requirements.

E) Cookies policy

Full details can be found in our Cookies Policy, including how to manage your cookies related settings. The cookies we use are small files stored on your computer or mobile device to enable us to provide some services and functionality (Strictly Necessary cookies), improve navigation and user experience (Performance cookies) and provide enhanced, more personal features (Functionality cookies).

F) Changes to the policy

You will be notified of any change to this Policy by email (at the address specified in your account) prior to the change becoming effective. If you continue to us the Services after those changes are in effect, you agree to the revised policy.

G) Your rights

In line with prevailing regulation, you have the following rights:

• Data access and portability
You are entitled to know what personal data we have about you and the right to copy, transfer, or move this personal data to a different company.
• Rectification
You have the right to have any inaccurate or incomplete personal data rectified
• Right to erasure:
You essentially have the right to “be forgotten” by requesting us to delete your data and stop processing it. Note that we may retain specific data for security reasons (such as fraud prevention), legal or regulatory reasons as well as in our back-up systems for a limited time (depending on databases back up processes and cycles).
• Restrict or objection to processing
You have the right to restrict personal data processing under certain circumstances or object to the processing of your data going forward (effectively withdrawing your consent).
• Right to be informed
This is achieved by providing you with the information contained in this Privacy Policy, Cookies Policy and Terms of Service.

H) How to access, modify or delete your personal information

  • Retrieval and modification: you can access and update your personal information through your Account settings, once you are logged in on the platform
  • Deletion: you can request for your personal information to be deleted at any time by contacting Koralgo administrators through the contact form.
