Four Turbo - AOC did not wish to authorise MOS at home base but deemed it ok to have a swim out of Gib. Spent harrowing minutes waiting to run out of concrete at 175K AUW! 2 internal tanks at 7.5K each gave another 15K of fuel.
Then had 4 internals for the long range trips out of ASI. Lurched off the runway and then ended up at 2000ft above the S Atlantic at the bottom of the toboggan.
Happy days as you say!!
