error when loading data

[joseberlines]

when running cell 2 of the first notebook I get:

SSLError: HTTPSConnectionPool(host='www.transtats.bts.gov', port=443): Max retries exceeded with url: /DownLoad_Table.asp?Table_ID=236&Has_Group=3&Is_Zipped=0 (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1123)')))

It looks a problem related to the connection to the API. Would it be possible to include as part of the repo the data to work with? Thanks
