Nimrod tail bumper....
.... did what it said in the book. Stude on first sortie, QFI newly checked out for this his first course. "OK bloggs, pull back smoothly and firmly ... (Voice rises by at least 5 octaves) NOT THAT FAR!!!!!!!!!" Solid clunk from down the back as the ventral strake crumpled allowing the bumper to take the rest of the impact, which it did satisfactorily. Oh the joys of L1!
