Bad day at the field.
1st crash: An Instructor took off with his own plane an old one covered in silkspan and dope. Never made it to the end of the runway aircraft rolled right and auggered in just after lift off.
Ailerons were reversed, and he did a pre flight check he just missed it. Pay attention out there.

2nd crash: My dad (another instructor) was flying our old trainer, inverted and decending in a left turn do to a low inverted pass. Aircraft started to lose altitude gave all the down elevator there was. too low to roll out . gave throttle the aircraft snapped right and, totalled, center line on runway. Flew the aircaft beyond it's capabillities. I mean trainers are trainers.

3rd almost crash: A newly solo'd pilot (2 months) flying his second aircraft a Bobcat. Took off, the aircraft was just above stall speed until 50 feet or so. The aircraft was rolling left and right the tail was sagging, I thought it was gone several times. Landed ok. Found out he had the prop on backwards. Attention to detail.

The reason I am posting this is to help the newer folks. I hope you get the point always check your throws before the first flight. I mean stand behind your plane and really watch. My Dad always does and he taught me that (pounded it into the brain). i haven't and a reversed throw yet.

Pay attention to details, as for my Dad's crash. Don't fly past your or your aircraft's capabillites.

have fun out there
