Bonus at Cranfield....
Just to add my tuppence worth....
I was an instructor at Bonus for a short time a few years ago..... A great place for the students with some good instructors...
Most instruction is on PA38 Tommahawks - a good machine - but they also have C152's, PA28,s and a pair of PA44's.
The only problems with Bonus are:
1) - They are expensive compared to most at Cranfield (maybe all except cabair)
2) - They can get very booked up - especially at weekends
Apart from that, they are pretty good...
