Currently only applicants with positive test results are hired. Since Dr Schwan is not working with Cargolux anymore the recruitment process is on hold. They have to come up with a solution soon to keep up with the present pace of 6 new pilots per month. They will continue this amount at least until the end of the year.
The average failure rate is about 80%, so 30 candidates per month is a rough number of applicants going thru the process.
