The 604 variants may come with or without slats
Really?? Never ever seen or heard of a 604 with slats - but willing to be re-educated.
The Danish Air Force has been using this type for SAR for many years quite successfully.
SAR is not the primary role of the RDAF 604s - they maintain a basic capability, but SAR is a fair way down the list when it comes to their role.
Turned it down, not enough money and a bumbling HR department turned me right off!
I hear you, brother!
