Thanks in advance, I can not get my head around the sumproduct

Database seperate sheet "DATA"
C column =date formated as mm/dd/yy
F column = Aircraft No ei, N123AB

I am trying to product a unique list of aircraft used for the month

I have the following but need to add the date element

=IF(SUMPRODUCT((Data!$F$2:Data!$F$3000<"")*1/COUNTIF(Data!$F$2:Data!$F$3000,Data!$F$2:Data!$F$3 000&""))<=COUNTA($V$129:$V129)-1,"",INDEX(Data!$F$2:Data!$F$3000,MATCH(TRUE,ISERR OR(MATCH(Data!$F$2:Data!$F$3000,$V$129:$V129,0)),0 ),1))

The V129 is where I want to start the list I estimate I will need place ment
for about 10 aircraft max
