I'm not sure, as I wasn't here when Mr. Byers made those comments, but I infer that he's raising the question of the access issue and the question of the launch of Radarsat-2 and the dispute that emerged over the question of launch after NASA refused initially to launch Radarsat-2, as they had launched Radarsat-1.
Je ne suis pas certain; je n’étais pas là quand M. Byers a formulé ces observations, mais je suppose qu’il soulève la question de l’accès et du lancement de RADARSAT-2, et le conflit qui a suivi le refus initial de la NASA de lancer RADARSAT-2, après avoir lancé RADARSAT-1.
