Fastest in one of HM finest grey flying trucks, 180kts off Scotland on JMC,
Slowest, 30kts for a 3 mile transit with two boxed rotor blades underslung
Made Oakey-Willytown IFR in one hop once (about 370nm)in a Seaking with 10 people and a poo load of bags, must have been in the region of 150kts. Amazing what you can do on the way home.
