The US Transportation Security Administration (TSA) has said the 1 August deadline for 100% screening of air cargo on domestic passenger aircraft was successfully implemented, but that the same goal for international cargo would only be met in a “few years” time. The TSA said it is continuing its work to improve cargo security on passenger flights originating in other countries, with TSA administrator John S. Pistole saying: “International air cargo is more secure than it has ever been.” “TSA continues to work closely with our international partners and is making substantial progress toward meeting the 100 per cent mark in the next few years,” he said in a statement.
