Having been flying for two decades I'm well aware of this.
What I'm doing is building a business case to investigate the creation specifically of the vortices that can suck large objects into engine intakes. The stronger the case I can make, the more freedom we'll get to investigate this widely. In my experience the two strongest arguments to get money for this sort of job are (a) loss of life, and (b) loss of revenue [sadly not always in that order.] So that's what I'm doing.
If I held the purse-strings myself, rest assured, I'd not need to make the case! All this anecdotal stuff however, is great and helps me a lot. (That said, there is always a finite budget, even for safety, and one has to prioritise.)
That said if anybody knows any numbers - hard pounds or dollars for estimated costs due to engine FOD ingestion, that would help me even more.
