This is the story of the 229.

In May 1940 German forces invaded the Netherlands in a massive surprise attack that would only last five days. To oppose the German forces, the Dutch air force only had a few dozens of first-line fighters and bombers of the types D-XXI, G-1 and T-V. Quite a number of them were destroyed on the ground by surprise attacks of the Luftwaffe and only a handful of aircraft were able to engage the enemy. In spite of the inferior material of the Dutch air force, individual pilots scored not all too bad against the Luftwaffe planes as we will see! One of these heroic missions was flown on 11 May 1940. The D-XXI pilot's lt. Focquin de Grave, sgt. Koos Roos and sgt. Burger took off in their planes nos. 213, 229 and 242 to escort two Fokker T-V bombers nos. 850 and 856. The task of the bombers was to destroy the Maas bridges at Rotterdam. The mission was a complete disaster. The bombers missed the bridges and on their way back 850 was shot down by German fighters. The 856 escaped, but only to be shot down on its next mission 2 days later!

Also the escorting D-XXI's were heavily attacked by German fighters. The 229, flown by Koos Roos became separated from his comrades and was attacked by three Me-110 fighters. After his plane was hit several times, Koos prepared to bail-out by releasing his seat straps and the cockpit canopy. To his great surprise, the canopy hit the engine of the pursuing Me-110 which went promptly down with a smoking engine! Koos discovered that he still had full control over his plane and he escaped in a cloud. When he came out, he was directly on the tail of the second Me-110. He immediately opened fire and saw the rear gunner collapse in his seat. Also this plane went down with a smoking engine.

Next, 229 were hit again and Koos lost his consciousness. Lucky for him, he was thrown out of his plane and when falling down he regained consciousness realizing that 'he was feeling lots of fresh air'!
With his right arm paralyzed, he managed to open his parachute with his left arm with very little margin since he was very close to the ground when the parachute opened.
Koos came down near the place where the 229 had crashed badly bleeding with a broken right arm, bullets in his leg and 20mm shell fragments in his head and left shoulder.

Also the Focquin de Grave was shot down; only sgt. Burger succeeded to land safely on his airbase. Focquin de Grave managed to crash land his 213 and he also survived his encounter with the Luftwaffe.

Sgt. Koos Roos survived the war, but he was tragically killed in the early fifties when he crashed with a helicopter.
