Wonderview - Poor Knights Islands

The B17 in Corsica is one of those Mediterranean wrecks we keep coming back to. There's a certain magic to seeing such a massive plane, especially knowing its history, resting on the seabed. We love dropping down and watching the light play on the fuselage, often spotting the huge conger eels that have made their home deep inside. The plane is surprisingly intact, considering its age, and you can still make out the cockpit, the gun turrets, and the wings spread wide. Navigating around the bomb bay is always a highlight; schools of barracuda often circle just above it, creating this incredible, shimmering curtain. It's a dive that rewards slow exploration, peering into every opening. We'd suggest going in the late morning, as the sun angle then really illuminates the wreck's structure. The visibility here is usually excellent, so you get a full view of the B17's impressive scale from a distance before you even get close. It's a site that really suits divers who appreciate a wreck with a story.

Cause
scuttled

On Valentine's Day 1944, this B-17G Flying Fortress was returning from a bombing raid on the railway yards of Verona, Italy, when it came under heavy anti-aircraft fire. With one engine destroyed and another failing, the pilot, Lieutenant Chaplick, realized he couldn't make it back to his base. He skillfully navigated the crippled bomber towards the coast of Corsica and performed a perfect water landing in the Bay of Calvi, allowing all ten crew members to escape safely before the plane sank beneath the waves.

Today, the B-17 of Calvi is one of the most famous and beloved aircraft wrecks in the Mediterranean. It rests perfectly upright on a sandy seabed at a depth of 25 meters, looking as if it could take off at any moment. The visibility is often excellent, allowing divers to take in the entire 30-meter wingspan. The cockpit is accessible, the plexiglass nose is intact, and the dorsal and tail gun turrets are still in place. The wreck is a stunning piece of history and a vibrant artificial reef, attracting a variety of marine life, making it a must-do dive for any visitor to Corsica.
