Never a problem with the Valiant
In the very early days of AAR, when we on 214 were doing the trials. Most of out tanking was done between our own Valiant's. Often fuel was passed from A/C 'A' to A/C 'B' and then A/C 'B' passed fuel to A/C 'A'. This was done several times.
When we started doing the night time transfers, and it was getting close to the bars closing, an A/C that had just passed fuel would often develop a snag that required it returning to base, leaving the recently topped up A/C to burn or ditch fuel so that it could land.
