I think it's a pretty good use for the PONG SU, she sat (round the corner from us seeping oil) in Snail bay for 8-12 months and then re-appeared at Clifton Gardens - where she resideded for another 4 odd, seeping more ballast and just looking like she was ready to decompose.
Would it not have been worth it doing a few live 20mm passes from f18's or similar before the coupe de grace, a 2klber GBU from a pig seems a little too easy ?
