Interestingly
Verlinden NOT on Caterpillar List as died Feb 21 1933 - (6 days late and never applied?)
On Wednesday, February 15, 1933, during a mock battle, the adjutant pilot André 'Quick' Kreit (° 6 July 1904 - Welkenraedt) and the Firefly of adjutant pilot Robert Verlinden came into contact with each other. The shock had severely damaged both aircraft and made them unmanageable. Verlinden was able to use his 'Irving' and reached solid ground safely, but Kreit crashed with his plane in Schulen, near Donk-Halen, and was killed. He has since rested in the Schaffen cemetery.
