Quelques jours avant le 70e anniversaire du Débarquement, les sites de commémoration sont sous haute surveillance. France Bleu Basse-Normandie les a survolés à bord d'un hélicoptère de la gendarmerie nationale.

Au total, 26 hélicoptères de l'armée et de la gendarmerie sillonnent le ciel pour surveiller l'ensemble des sites sensibles du 70e anniversaire du Débarquement. Avec une attention accrues sur les lieux de commémorations et sur les alentours de l'aéroport de Caen-Carpiquet.

Repérer toute présence suspecte

Pour France Bleu Basse-Normandie, Didier Charpin est monté à bord de l'hélicoptère EC135 de la gendarmerie. Cet hélicoptère est habituellement basé à Rennes. Son équipage composé de deux pilotes et d'un mécanicien a reçu l'ordre de venir renforcer le dispositif de sécurité avec une mission prioritaire : scruter le sol sur environ 1.000 km². Et répérer toute présence un peu trop isolée et donc suspecte.

Une portée de 20 km

Dix minutes après le décollage de Carpiquet, au-dessus de Ouistreham, l'hélicoptère effectue une large boucle en survolant la plage et les vastes installations pour les cérémonies. À 300 mètres d'altitude, à une vitesse de 180 km/h, le mécanicien observe sur son écran les images captées par une caméra fixée sur l'un des patins de l'hélicoptère. Cette caméra a une portée de 20 km. Autrement dit, la personne filmée n'entend même pas le bruit de l'hélicoptère alors qu'elle est dans l'objectif des gendarmes.

Images transmises en direct au ministère de l'Intérieur

Si un comportement suspect est détecté, une brigade au sol sera imédiatement alertée. Ces images sont également transmises en instantané à Paris au ministère de l'Intérieur. D'autres corps d'armée auront des mission plus musclées ce vendredi lorsque les 19 chefs d'Etat et de gouvernement seront rassemblés. Par exemple, l'armée de l'Air survolera les sites avec des tireurs d'élite à bord de ses engins pour parer à toute intrusion aérienne.
