EFATO just after rotate - def a Mayday call if time permits to alert ATC and aircraft in proximity (prob not on 121.5)
Scenarios
1. a/c tries to land ahead on runway, poss overun, injuries & runway closed
2. climb established on 1 engine, assess options
a. go around & land o/w, poss u/c failure, injuries etc
b. remaining engine nominal, no fire in other, controls responsive, climb to safe alt, cruise to max land wt keeping alternates optional
(One working engine can keep a/c in air but I wouldn't risk continuing to Alicante)
If option b then approach freq would provide best option vs tower
Prof opinions welcome but I doubt the AAIB will be critical of the pilots
Job well done!
